This is PONG! You will be put up against the computer. The ball will randomly spawn and use the arrow keys to move your paddle up and down. Choose from Easy, Normal, or Hard modes, and be aware of the computer's incredibly good aim (particularly on Hard Mode). And there is a secret custom GATLING mode. (if you want to win, you won't do that mode) If you find it, please don't post in the comments.
Thanks to @Dude7685 for making the project, and thanks to Allan Alcorn for inventing Pong.
