The Slimes are taking over, You are a warrior trained in the deadly art of slime-jitsu (it's a legitimate thing ok) and you aren't going down without a fight... Jump on things! WASD/Arrow keys to move SPACE or Z to throw shuriken P to pause/unpause the game. Click the mute button in the top right to toggle sounds.
Hacked version of the game, still only took me like twenty seconds to fix up though.
