WARNING: THIS GAME CONTAINS THEMES OF BOOBS OF LUDICROUS SIZES ON FOXES OF REASONABLE SIZES. IF YOU DO NOT LIKE THAT, TURN BACK NOW, BECAUSE I FORGOT TO PUT A WARNING IN THE TWINE GAME ITSELF.

Unlike most races, which tend to be hypers in approximately 1 in 1000 cases, foxes have been recorded to be hypers in approximately 1 in 1 cases. While normally not an issue, it has been noted that the city of Bwom, which is composed of almost 95% foxes, tends to be a focal point for Extreme Expansion Events (EEEs). This is a dangerous phenomenon where a hyper will, via some stimulus, continue to increase in size with no apparent limit.

If you believe that a fox around you is experiencing an Extreme Expansion Event, alert the local Bureau Of Out-Of-Control Hyper Suppression (BOOOCHS) branch and wait for them to defuse the situation. Do not, by the fox's request, click and drag your mouse across the fox's tits in order to cause them to grow further.

If you have been pinned against a structure and/or the ground, have just witnessed your local Bureau Of Out-Of-Control Hyper Suppression (BOOOCHS) branch office being flattened by a pair of breasts twice its size, or are living on a continent and/or planet in the process of being enveloped by boob, politely disengage from the situation and move elsewhere.

In the event that you have been rubbing and/or groping a fox's tits for greater than 5-10 minutes, do not then proceed to do the same to the next nearest fox, even at the insistence of both of them that you're simply "sharing the love". This will cause a Growth Resonance Phenomenon (GRP) whereby a combination of practice, experience, and ancestral might will influence the next hyper you touch to grow at a greater rate than they would have otherwise.

This has been a Public Service Announcement (PSA) by the Bureau Of Out-Of-Control Hyper Suppression (BOOOCHS). Remember: An unstimulated hyper is a happy hyper!

[-------------------]
Note: This game is still in a prototype phase, but I do know what I'm going to do with it. It really just started as a way to turn that one fox model with jig ol tiggly bitties that I used for quite a few pieces on my FurAffinity Gallery (wink wink go check it out I write stories) into something that could be modified dynamically, with a slider, rather than having to copy + paste + resize + rearrange the nodes every time I want to make a large fox larger. Then, y'know, boobs happened and now I have a game. Sort of. Probably could've put this into Yuri My Beloved if I had two weeks to burn and an extra soul to sell, but I prefer to only ever add content to my portfolio, not replace it.

But if you have suggestions that you think are workable by someone with knowledge overwhelming of Twine-Sugarcube and like 20 hours of crying over Javascript, drop a comment or gimme a shout somewhere. If you want to see something in the world, make it yourself, but if you can't do that, ask me!

The mere circuitry has grown in resilience and now even my own machinations bear fruit. The game is now entirely mobile-compatible, and the saves function correctly AS LONG AS you poke around the settings to figure out what you need to do to make them work.

Can you give info on when we can expect the next update? Not trying to rush, its just very easy to tell the game is in its very early stages, I do think it could be a lot more fun once finished though.

(+1)

I'm slowly padding the foxes out with features, like improved bra visuals, jiggle, additional minigames, more math, better math, rewriting all the math because ugh it was close but ever so slightly wrong, and typing up log messages and upgrades oh my.

I don't really like posting unfinished updates to the general public. I could see that this was a large project and I really liked what I had done so far, so I went ahead and posted the first two updates, but I'm entering a span where everything I do make will look and feel horribly unfinished . Not the level of quality I want to make the face of my creation, even if it is marginally more content than the last update.

However, I am posting occasional beta versions on the discord servers I'm on. Possmonaut's server, TsukoEX's server, and the Extreme Breast Expansion server are the main three, and I'll occasionally toss out a demo of whatever I happen to have done every once in a while. It's a lot less hassle and it's a lot less stress than doing it through itch.io.

Also, saves aren't cross-compatible between versions so I don't want to introduce the upgrade system to the public version until it's completely finished (bugfixes notwithstanding).

I have been making less progress than before, as finals week has been coming up and ough I gotta balance the upgrades. I cannot give any honest assessment of when you could expect another update. It is coming, though, rest assured.

(+1)

Hope you drop another update soon! Not trying to rush you though, just really excited for ANY new expansion content to be honest. Underserved fetish, at least in terms of games. That are good, anyway.

May be some time, but rest assured that work is continuing and I only took 4 hours to turn a corner into a slight bevel this time :)

(+1)

Gotta love giving her a bra the size of a few football fields and re-enacting a nuclear explosion with fox boob, 1000000/10

Would recommend

(+1)

Hoping for a side view in the future

(+1)

Ough I'm not a good artist. That would also be some fun new math, figuring out when the boob begins pressing against the ground and how it deforms from doing that. I'd love for it to be, of course, but I have done deceptively much with deceptively little, and I'm going to have to be a little more honest about... having skills in order to make that work.

(+1)

Discord server?

May start my own (nsfw) server someday, but for now I'm hanging around Possmonaut's, TsukoEX's, and the Extreme Breast Expansion discord servers, you'll find me there. I've also got a FurAffinity account, RoanneTheWolf, which you can message as well if that's too much trouble.

(+1)

The game is amazing! And can you add any objects to it for comparison, otherwise after a certain size the growth is not felt. For example: houses, planets, galaxies, universes

That's the plan, yeah. I just have to find or make enough monochrome svg graphics that fit the art style. 

(1 edit) (+1)

Can someone pass my record before the NAN? 

(+1)

Not too hard, with a lil luck. 10,000 power is around the right amount to get a few zeroes per second but not totally blow it out of the water. The limit is somewhere around 1e308 inches, give or take a few digits, and the universe is 4e28 inches across. That leaves you with a little under 280 digits- you don't yet have 60.

(+1)

well, from exceeding the limit so much, this happened

That is. Very strange. People have exceeded the bit limit, and while it of course breaks, it hasn't broken that way.

By chance, have you enabled cookies for that site? Twine does... something with cookies when played in-browser and I bet that could be one potential thing that could've gone wrong.

Unless you exceeded the bit limit for more than is a reasonable amount of time and that was the result?

(+1)

It was as easy as using an auto clicker, use it for 15 minutes waiting for rebirth and that's it.

(+2)

I like this game i hope it will fun like Yuri My Beloved

(+1)

Just an idea - how's about adding a mood modifiers like:
-Slows the growth
-Speeds up the growth
- Gives a slow steady growth on their own etc. ? 

(1 edit)

I've got upgrades that'll speed up the growth and provide passive growth, but moods... I suppose they'd have to be events? Events that appear at random intervals with random effects.

Maybe something like the golden cookie in cookie clicker where it appears for a short time and gives you a temporary bonus. Perhaps if you let it expire, you get a debuff instead.

...I'll consider it. I don't want the game to get too complex. At least, not at too fast a pace. Unlocking them via an upgrade later on seems perfectly viable.


For specific foxes, because the prestige hinges upon the upgrade system, I don't want to give random chances to have a much easier or harder times grinding out the next upgrade due to the specific fox's disposition.

(+1)

It sounds pretty reasonable. Looking forward to look for your progress in the future. 

(+1)

I am sad to announce that at 2122278.6x power after just one (1) click i get a NaN and a broken window

(+1)(-1)

(also here is my previous record)

Yeah, the code kind of just spills out the end when the numbers get too high. That appearance is a visual bug, by the way, which can be fixed(?) by increasing the stroke width in the settings.

(+1)

Not sure if you already thought of this (and if so peanut gallery comment) but I know there is a mathematical function for things approaching a certain number (like calculating something infinitely close to a value) but as I typed this I realized I was being silly and it's much easier to code if > than set to x so... 



Boobs

(+1)

Yeah, I'm already using that for a few things, like the squish.
y = n - (n-1)/x {1<x<inf}.
When X is 1, Y is 1, but as X increases, y gets closer and closer to n without ever reaching it. It's good when it needs to always perpetually increase the more you interact with it, but still need to have a hard maximum otherwise it'll look strange.

As for using that to handle floating points, it's not possible. At least, not the way I'm handling it. 1.7e308 is, give or take, the maximum value for a variable I use, but the problem with that is this means that I can never, in any function, ever exceed that number. I can't exceed it, detect that I've exceeded it, then divide it by some value, because the exact moment it exceeds that value, it becomes infinity and there's no reclaiming my original number anymore.

I'll probably end up just having it detect if the value is infinity, in which case it'll display the largest fox it can without letting it grow anymore.

(+1)

I was suggesting it more for the bra to prevent it from looping back around on itself (clarification men it is important!) also I just love how finagally computer math is with super massive numbers and Im really impressed that you solved it the way you did! 

Couple more  peanut gallery comments when the fox does reach "max size" you could always cheat! Shrink the fox model and slowly decrease the frame to give the 'illusion' of getting more 'uge without the boobs incrementing past a certain number.

And last I'm not sure if this would be easy or impossible with how your math is set up but having 'scaling rings' that sorta appear around the edge then shrink around the fox would give some sort of visual reference to how big she is without relying solely on the single number (size of a house, size of the moon, the sun, the observable galaxy etc)

Also thanks for the time your putting into this! You are amazing!

(+1)

I'm gonna go for reference objects as best I can, but that's gonna be a decent amount of work including a sufficient number of .svg files in a way that still moves. Plus, references somewhat go away after a certain point.

2 ideas

1being able to date/interact with her.

even if it's something simple like a menu where you have an event that's a text box you can trigger on demand with a few variations based on her size at the time.

like going to a fancy restaurant near the starting size it would describe her breaking the door frames and the table,

and near the end sizes IE

("she turned toward the restaurant bumping her cosmic sized breasts into the restaurant as well as the nearest 100 galactic super clusters around it, everything sinking briefly into her bosom before bouncing off, flying off to parts unknown, you both decide it's probably best to order delivery.")


even if it's not super Indepth being able to do something with her would go a long way to adding depth so she's not ONLY  a big number.



2 instead of like most idle/click games have it go faster the longer it goes on.

I played a game where boob size is damage, but the enemies didn't increase in health. so, you beat them faster and faster it's the closes I've felt to the runaway growth in many BE growth stories.  

with you already doing something similar to that even if you need to start slower, 

really leaning into the growth accelerating could fix the slog many idle/incremental games become after the halfway point.   

Log messages are something I'm planning to add in the box that currently has the buttons in them; short little bits of lore and fluff that make the world seem a little more alive. The upgrade system, as well, is all going to have unique descriptions. Going to a restaurant, though, is a very neat idea, and I'll be sure to include that a time or two.

I did like random renamon boob clicker x, but that's mostly because it visually displayed particularly large sizes. Nothing else does that. Except now :)

It already does go faster the longer you go on; finding a new fox to grope will reset the size but increase how powerful your groping is. It's still a prototype, so the exact mechanism does, uh... exponentiate, after a bit, and the end of the game as of right now is the bit limit.

(5 edits) (+1)

I know it goes faster the longer you go hence the "with you already doing something similar to that" in my op.

I'm saying continuing to emphasize that will give it a nicer "game feel" in reference to   

" This is probably the only update that'll make the main gameplay loop faster rather than slower."

in the development log notes.

and if I may be blunt with my influences THIS has visual novel dating elements, the first coffee date she talks about her favortie drink but at max size she's sitting at home taking about how she can't go there anymore with a coffee cup in here cleavage. something like that but scaled up to your preferred sizes (minus the CGs)

the logs from Yuri My Beloved are good, my point is the interactivity.

 having some repeatable Logs that you could do any time that have a few outcomes based on her size at the time (kind of like what MagnusMagneto does for FMG Life Sim if you've seen it, also made in twine)  in addition to the normal ones would be the cherry on top.

you don't need to do any of this, what you have is already sold gold, these are just the few ideas I had that could add something while also being reasonable to implement.  

(+1)

Looping events with variable results are something I haven't really considered. I think there are a few issues with that, specifically my workload and the format of the game. Any action that appears is interruptive rather than supportive; the logs work out because they're unique and interesting, and I do plan on making as much as I can. But events that repeat, rather than just being referenced with a new spin like the donuts in Yuri, would require enough variations to keep them fresh- which, for the sizes they reach, is an exponential workload.

I am, however, going to give the player abilities with a cooldown that have visual and mechanical effects both on the gameplay- one of which being the bra. Another will involve zooming in, and there may be additional tails somewhere in the mix. The upgrades for such abilities will be similar but different, and... I dunno where I'm going with this.

your idea has potential. I'll keep it in mind, but this game's core loop is inherently very simple and individual scenes go against the loop. Maybe when the rest is made there'll be room for it, but before then I'll focus my efforts for what I need to lay out in advance.

(+2)

Literally no one on the planet:

Only the most sane speedrunner ever: Infinite Boob WR

Run notes:

  • Timer starts on first grope, ends when infinite is reached.
  • Ran on Opera GX cause I'm a gamer.
  • Could be optimized better, legitimately causes wrist pain.
(+3)

That is beautiful.

I'm thinking of adding some accessibility settings;  the ability to click rather than drag, different colors for those who want them, the ability to switch to a kemonomimi rather than a furry, metric units, the works.

...And a bra, and a better method of upgrading than just a prestige mechanic that gets a little too exponential in its growth.
...And a zoom feature. And the ability to adjust the line thickness for those with weird computers.

Again, this was just a prototype.
Here's a newer one, as a reward :D

(+1)

AN UPGRADE SISTEM? now this is the perfect game. time to spend hours playing 

Not there yet, but it's coming, don't you worry.

(+1)

ive achieved  NaN universes yet again

Dang as the first person to 'officially' grope boobs to infinite boobs in seven minutes flat, I must say this is quite the honor :D

(+3)(-1)

Might I suggest confining the breasts to the first camera until they fill the box before zooming out? Like once they touch the sides they start pushing forward.

(+2)(-1)

I wanted to make it so that they'd never take up less size on the screen than they did at a smaller size, because screen size = more room to move your mouse. I probably do need to increase how much it's zoomed in at the beginning, though.

(+2)(-1)

There's a lot you could do with this prototype tbh, this is really impressive. Just depends how big (no pun intended) you wanna make the scope of it.

Just some random ideas that popped into my head:

- A system where every fox girl is unique and has a randomly generated name taken from a list, with unique quirks (a short physical description in text describing her appearance from a list of variables like fur color/eye color/hair color/hairstyle/etc., varying growth speed, slightly different boob shapes/breast firmness, personalities), as well as a dialogue box with random barks (also no pun intended) every so often commenting on her size and the intensity of your actions, and a way to ""keep"" a specific girl if you want to revisit her later.
- Different ways to achieve growth, not just by rubbing the boobers. Such as headpats (which are unlocked right away and... I dunno, slower...? unless maybe you do it on a foxgirl with a shy personality or something), ingestion of various drugs/substances or milk or something that give a fixed growth rate for a certain period or give short bursts of growth and are unaffected by your hands' power multiplier, inducing lactation, (implied through text) sex, etc.
- An option to actually call B.O.O.O.C.H.S if you want to shrink a specific girl for whatever reason, assuming the first idea actually is a thing, as well as an option to wait (not in real time) to reduce your power multiplier back down.
- Kink toggles (such as humanlike faces instead of full-furry for those who prefer their foxgirls without the long furry snouts, removing lactation triggers if that becomes a thing, etc.)

Hell, if you REALLY wanna go crazy and have the time I bet this would work just as well for butt and belly expansion visuals, if you're into that.
Though that would probably have to be a unique quirk on girls where those parts grow instead of the boobs and you can rub those instead.
As cool as it would be to have all three at once on a girl and it would help add a further sense of scale comparing the different bodypart sizes (whether naturally through getting lucky with quirks or by overspending on some crazy drugs to allow all three at once or something), that seems like it'd be a major pain in the ass to make work. And belly wouldn't be visible anyway if it's any smaller than the boobs.

Point is, take it in whatever direction you want chief. I'm looking forward to ANY potential updates to this no matter what they may be!

(+2)(-1)

Those are some good ideas. I probably won't deal with any other parts, even though butt is certainly viable, because I believe in the concentration of kinks. A game with full focus on one thing as both the means and the end is highly focused and tends to be rather hot, whereas one that lets you go in fifteen different directions tends to lack depth and dilutes the horniness for me overall.

I'm thinking of using the "abilities" system some idle games like clicker heroes do, where it's additional things you can do with a cooldown. The one I've already implemented clothes the fox in question, decreasing growth while the bra is intact, but as you grope her she visibly squishes more and more against it until it snaps, making the fox grow twice as much as she would've otherwise. Like the Claustrobobia images on my FurAffinity gallery.

Gonna make a human head a setting, since that's about all it'll take to accomodate. Easy enough. And if they can't even stand animal ears and tail... well, too bad, I'm still the artist, author, designer, and programmer extraordinaire. I get to choose what to make.

I was thinking of making a character gallery to view foxes you've already grown.. A set of japanese syllables, two or three of which are selected at random to form a name like "kukiko" and hope that nothing that's generated is too offensive in the language. Shrinking is against my and the foxes' belief system, hence the new characters when you need a smaller one. Descriptions, moods, and personalities will take a lot more writing effort, but I'm sure I could slap something like that together.

I'll probably also add a creative mode, maybe unlocked by password or at the ending, where you can just customize the exact things you want on the fox rather than having to deal with a power rating that's too high and such. The power rating's something entirely temporary, by the way, I'm going to use a system of upgrades like I did in Yuri My Beloved.

Nevertheless, this is the most detailed response yet. If you send me your discord username, I can show you the bra prototype I've made. Not enough change for a new release, but enough to get feedback on from a few beta testers.

(3 edits) (+1)

Sounds great! I can understand the strengths of a "focused" design philosophy like that even if I don't entirely agree. But regardless, keeping the scope not-too-crazy so you know you can achieve it reasonably is a good way to go imo.

The character gallery idea sounds good. And honestly, if the weeb-y nature of it ruffles anyone's jimmies, well, it's as you said. your game, so more power to you. everyone's a little cringy/cheesy at times, but hey, whatever makes it hotter for you in a simple browser fetish game is what works lol. And I also think it'd fit.

Hope headpats are something that is possible to be honest. Come to think of it, it probably wouldn't be impossible to also add some sort of simple tail-swaying animation specific to when you're growing them through headpats even if just a few frames, the tail is already there and just needs to be mirrored for the opposite end of the animation.

(1 edit) (+1)

A tail swinging animation is difficult, cuz I'd want to properly animate it rather than just mirror back and forth. It wouldn't fit with the quality otherwise. Headpats I can do, though it becomes difficult when the head is no longer within patting range. Maybe I try to see if I can manage a zoomin feature...

(+3)(-1)

I have been given great power... And I refuse to use it responsibly!

(+3)

The responsible thing to do would be to grope that poor, attention-deprived fox.

(+3)

Is it only for me or do the boobs just dissappear immediately?

(+2)

On mobile, just the slightest touch of your fingers is enough to cause the boobs to outgrow everything that ever was and ever will be, which is somewhat bad for the code. I haven't gotten around to fixing that.

The game's much better on PC.

(+3)

PC fox: takes time and effort but eventually results in mass infinite fox growth as you go from one fox to another

Mobile fox: even just walking into Bwom results in the entire fox population instantly outgrowing everything without any warning

(+3)

You in particular have that effect on foxes. I'm working on identifying the issue, and I think I've found it: You're too damn cute and they just can't resist.

Also there's text in the input that should be strictly numerical, meaning that I'm trying to stuff a word into a place a number goes, meaning that it's literally telling me outright "That's not a number", which is the same failstate as "the word 'infinity' isn't a number either". But you being too cute is probably the issue.

(+2)

Well sounds like they're upset the limitations prevent them from getting any bigger. After all they could be so much bigger, but they're stuck at just plain infinity. Doesn't help that there's other universes worth of foxes who could be growing as well...

(+1)

"Could be-" they are. Yuri's right there in the next one over, after all.

YES!! THE NaN universes wide! LESGOOOO

oops. a little overdone. XD
I think I beat this game by accident

love the game, maybe add some colors or something to the background so we can get a sense of scale and itd be even better

awn, i cant achive the NaN number, really cool concept btw.

I did read your story in FurAffinity too, really nice. 

keep up the gud stuff 

You can.

ANOTHER GAME LESGOOOOOO.

time to achive the NaN number again
