Object of the game is to score 20 points by getting the ball to hit the ground on the other side of the wall. You're not allowed to touch the ball 3 times in a row before the other player touches the ball. When you score a point, the ball is placed in the air so you can bounce it off again. Have fun! Player 1: Arrow key left = move left, Arrow key right = move right, Arrow key up = jump; Player 2: A = move left, D = move right, W = jump.
