Click the green flag to start the game. Move the ball around with your mouse, and don't let it touch the x's. In normal mode, try to avoid the three x's that move randomly around the screen. In clone crazy, one x has the ability to clone itself. Luckily you have invisible helpers that can destroy the clones. Before playing clone crazy, adjust the slider to to adjust the number of helpers.
I decided to make the score display because it doesn't look very good to just have the variable. Post you score.
