What started out to be a physics demo, turned into this game wOne! Using 2D physics: Bounce, Gravity, Spin and Friction the player can bounce and spin around each level. The momentum of the Wheel carries the wheel up slopes and into places of difficulty! Using Line intersections for the collision, the Wheel is given a very precise position on each surface, even corners. This was a problem to start with, however, was overcome by using a different collision line to the one you see!
