Press space to start. The green paddle will follow the mouse pointer (cursor) and will bounce the ball. Try to keep the ball away from the red line! If it does hit the red line, just press space to retry.
I was trying to get the paddle to hide when it's a game over but I couldn't find a way to do that. Hopefully it doesn't ruin the "game over" screen to much. It would be helpful if you could comment on this project and let me know how to do it if you know. Enjoy!
