(Kinda late on updating this review.)

Basically it's an inflation sim sandbox game, you run around, inflate, stretch out to then inflate even more.
It's super nice to see an unabashedly inflation-focused game for once, especially a sandbox where the player can do whatever they want.
Normally that'd make for an easy 5/5 from me, but...

Issues:

1. Stretching out your max capacity to a decent size at any sensible rate requires basically minmaxing, grinding carefully for a surprisingly long time for a game that doesn't have much content. Even if the stretching speed was doubled, it'd still be too slow. Heck, I used Cheat Engine for 10x speed and it still takes a while. (There's debug hotkeys though, numpad, I think?) IIRC there's a few meta ways to speed up stretching, but I never did it.
2. It's in development hell. Dev 1 quit pretty early due to some IRL issues, and dev 2 didn't last very long either, both leaving the game in an unpolished, unfinished state where there's really not a whole lot to do. The whole FL server just kinda feels like it gets depressed whenever anyone mentions any FL projects.
3. The game does that usual thing where there's no belly bone or corrective shape keys to protect the belly's shape, so any animation involving bending over, twisting, etc. just results in the belly stretching and squishing in awful jaggy messes.
4. Interactions are janky as hell, it's easy to warp through walls and ceilings, or somehow interact with something in the next room over.
5. No depth to anything, not much reason to do anything either, like helium is cool and all, but the map's flat, so floating doesn't really do anything for you, even though you spent 5 hours grinding bowel capacity. There's money you can find, but I don't think there's anything to spend it on. That kind of thing, no depth, no X -> Y -> Z.
6. The map takes a while to run around  sometimes, made worse by the fact that all the game's content right now is spread out into effectively three separate zones that you walk between, and the map itself being a stock asset meant for more content than what's here.

I dunno, I could probably go on, but this review's already too long and I'm working entirely off memory here as I haven't played since the last update.
Also I'd rate it lower, but I'm getting tired of Itch thinking I don't like inflation solely because I keep rating inflation games down.
You too, Steam.

Don't get me wrong, the game's still worth at least trying out, I just don't think there's enough reason for someone to play it for longer than the "oh, this is pretty cool" honeymoon phase, since there's simply not enough content to mess around with.
