To play, all you have to do is click the green flag and move the paddle around, trying to hit the ball. Every time you hit the ball, the score goes up by one. Try to get a high score, and when you feel that your score is high enough, comment what it was down below. There is a 1/4 chance that the ball will hit your paddle without you moving it at all. Have fun!
This came from the user with the name of Tstan2004. His project was called "Space ping-pong" which is similar to this, but with space objects. I did not copy him, I changed it up a little bit, please do not go yell at me in the comments. Anyway, have fun with this.
