Use WASD or arrow keys to "move," mouse to aim, and space to fire. Aim at the enemies, and don't touch them. Slime them out to get Aura, which summons a bunch of cursed MLG stuff. If you lose all your HP (the bar on the right) you lose the game. Now stop reading this and go play the very nice and beautiful game!
A 24-hour game I made as a challenge for myself. Had to spread it over a few days, but it was good fun to make.
