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!
I created this game with much help through the pong tutorial in the tips section. It showed me how to construct the code and controls of the game.
