Really cute game that's strangely addicting to play.
Would really love to see more variety with the inflation shapes tho instead of the "three B's" (Belly, Boobs and Butt) Do you think you could make the enemies (and yourself) inflate until you're completely spherical? (aside from your head, hands and feet poking out of course)
Maybe add some blueberry inflation to the game as an weapon/powerup? You could have a hose gun that sprays juice on the enemies that causes them to inflate into blueberries?
This could tie into a bubblegum item that allows you to deflate yourself by blowing bubbles but it also risks inflating you into blueberry and this could change the mechanics a bit by forcing you to move slower and roll yourself around?
I think blowing bubblegum could work as a risk/reward item in that it might inflate/deflate you with how big you blow the bubbles correlating to the risk of inflating/deflating.
Also I would love to see some variety with the clothes on yourself and the enemies. Maybe have buttons pop off your shirt and jeans as you're inflating? The same would also work on the enemies too of course.
That's all I can say for critique, great game so far and I can't wait to see what you come up with next!
