This is a nice polished game. Great art style! The game play works well, but is a bit slow for my taste (unless you grab a speed powerup), and it's too easy - it almost seems like you can play forever, though after a few minutes some real enemies appear. I would also add that enemies drop powerups (or mutation / XP points), maybe even powerups that disappear after a while, which makes the movement and positioning more interesting. Anyway, that's nitpicking - it's still among the top games of this jam!
