Move your mouse to control the paddle. Don't let the ball touch the red! If there is no one else online, you can put two windows side by side and play against yourself!
NOTE: If your opponent moves their paddle very fast under the ball, right before the ball is about to hit it, then it can APPEAR as if the ball is bouncing off air. It is not, that is just a visual glitch. Please leave your feedback in the comments!
