As you navigate through the obstacles, you must collect various power-ups to get you out of the tight situations that arise. Graphics are 2D and rendered from a top-down perspective. Control the top with your mouse or the arrow keys - make sure to use small mouse movements, as that top slides all over the place. It spins differently on different types of plates, slows down in radiation areas and gets boosted by energy fields. Jumping is tricky.
