Very entertaining little inflation game~
My own criticism for it is
1: I'd love some more customization options; hair style, hair color, shirt color, maybe even different outfits if that's at all possible, different skin color, eye color, just more customizations
2: I'd like the special inflated (spitter, the one with the hose, blimp) to be more distinguishable I guess, hard to know which is the spitter off the bat when there's a hoard barreling down on you. and if anything wouldn't mind if the blimp was more threatening, sure they take a lot to pop but they take just as much as everyone else to render them floating, at which point they almost always get knocked out of the way by everything else and they're just not a threat at all.
I really enjoyed this game and hopefully you add more to this game and continue on making more games in general!
