Wall ball. Use the mouse to move the paddle up and down and bounce the ball back at the right wall. Every time the ball hits the paddle, you get 10 points. Once you reach certain point plateaus, the difficulty will increase by speeding up the ball and shortening the paddle. When you reach these plateaus, you will gain an extra life. If you miss the ball, you will lose a life. WARNING: If you have a history of seizures or are prone to seizures, please DO NOT play this game. This is a very serious warning.
