2 player ping pong! I advise the player on the left to use w to go up and s to go down. Hit the ball to the other side. If it touches the edge of the left screen the person on the right will get a point. If the ball touches the edge of the right screen, the person on the left will get a point. ( the points are at the top the one on the left is left players. the one on the right is right players.) If you are on the right I advise you use up arrow to go up and down arrow to go down.
