It's alright. For once, one of these games has a huge, round belly instead of some ultra-lazy bone scaling or whatever. The belly looks nice. For reference, the belly on the game's page as of the time I'm writing this is maybe... 1/3rd full.

Anyway, it's... kind of an idle game. You inflate her, there's a few meters to manage, she gets huge. 
There's three(?) endings. I've seen three different endings, but I feel like something's missing.

Really the only actual issue of note is that the game's very slow-paced, which kinda sucks due to how simple the game is.

Hoping the dev continues updating. More tools, more balance, more things to do with her, maybe a "postgame" after she's maxed? Whatever, I dunno.
Rating this one 3.5 stars, but I'm rounding up. If it wasn't so grindy, I'd give it a solid 4.
