Click the green flag and the ball to start the game. Both must be clicked or else one won't function. Bounce the ball off of either your head, back of leg (hardest) or your arm (easiest). Keep it going as long as possible. This goes faster than my last games, keepy-uppies, and in this one the ball goes to a random height, though always a reasonable one. It's better in full-screen mode. Feel free to remix and comment.
