Put P1/Red on the left side and P2/blue on the right side of the computer. Each of you get a pencil, if the ball touches red, red gets a point, same with blue. use the pencils to poke the buttons farthest from them to move the ball in that direction; red would press 0,p, and l while blue needs to press 1,q, and a. You may not press those buttons with your fingers as you may block, swipe, and slash to press them and defend from yours being pressed.
This is all original, except for the music.
