You only get one disc with which to slice up the wretched android menace which the noble and holy DISC-MAN has sworn his life against. After you fire your disc, you are vulnerable and must parkour and sneak your way over to where it landed before you can throw it again. Survive as long as you can as more and more of these fiends swarm the arena.

Instructions are repeated in game:
A - Run left
D - Run right
S - Hide in alleyway
SPACE - Jump
HOLD LEFT MOUSE - Charge disc
RELEASE LEFT MOUSE - Fire disc

Wall-jump by touching a wall and pressing SPACE or running in the opposite direction. Retrieve your disc by touching it.
