Very basic game, but pretty cool, there's a few kinds of bellies to look at, and the game even does pretty okay with mixing different "fillings" to change the shape of the belly a bit, like simultaneously having hard and soft things in there to make a smooth belly with few lumps.

I will say that the game is WAY too simple though, you solve a puzzle a ton of times to grind mana to let you do belly stuff and unlock new belly stuff, and there's no save function, so it's really only good to play this one or two times total.
Probably should've given the game 4 stars (4.5 if possible), but eh, the game's simplicity isn't really a dealbreaker, I guess.
