Living The Dream: Crash Test Dumbass!

Click to move vaguely in the combined direction of the GryoBlock and where the mouse is pointing

WASD to rotate

Knock over things for points

Power-Ups are scattered about

The game is over when you find the portal home or light on fire. Or both.

The only major problem that might screw with you would be issues with momentum. If clicking makes you go backwards, don't move for a solid 5 seconds or so, let the GyroBlock come to a complete stop and you should be able to control your momentum in the proper directions again.
