You are a snowball in hell and have to stay alive as long as possible. Collect snowflakes and grow bigger. Avoid falling into the bottomless pit and burn out while fighting off pesky little devils. ARROW keys to move and jump. Hold arrow key for higher jumps.
Stay alive as long as possible and earn bonus points by rolling over little devils. Beware though, you must attack them from behind, otherwise they will use their pitchforks to push you off platforms.
