You are a ball that just cannot stop bouncing (jomping?). Your only goal is to get from one end of the obstacle course to the other. The only things standing in your way? Lava, spikes, swinging balls, and your own reflexes. There are trampoline areas that make your ball bounce higher and other spaces that cause it to bounce lower.
Control the backwards or forwards movement of your ball with the mouse.
The water powerup will make you temporarily impervious to lava.
