To play my pong game, just click the green flag (in the center once you first start) in the top right hand corner to get started. To move the paddle, click the right arrow key to go right and the left to go to the left. The object of the game is to keep the ball up, or to not let it hit the ground, or you will lose points. Good luck!
For this project, I used the "pong" guided lesson located under tips.
