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.
