Ok, this is actually more fun than I thought it would be! When you showed us some gameplay on Discord I thought having to inflate the enemies every time could get frustrating after a while, but it actually forces the player to switch strategies mid game in a way that kept the main loop interesting.
I agree with the people who said this game could benefit from more content, but besides the obvious "more enemies and power up variations" something I'd really like to see is some sort of side effect to when your enemies explode, like stunning or knocking back other nearby enemies.
