WASD or arrow keys to move, you're the green cube.
The goal is not to defeat your opponents, but to dodge them before they kill you.
Purple cube(Shotguneer) will move towards you and shoot three bullets. Dodge them. If they hit a wall, the Shotguneer takes damage.
Black Cube(Dread Seeker) will fly towards you and take damage if he hits a wall.
The Devourer of Pain will bounce around the arena, and slowly take damage and get bigger. If he hits you or another enemy, he gets bigger and heals. He will deal you damage if he hits you.

Now you know the rules. So get out there, and SURVIVE! THE ARENA DEMANDS BLOODSHED!
