Single Player: Use arrow keys or WASD to move up and down. You're the blue panel. Multiplayer: Player 1 (Blue) uses just WASD, while Player 2 (Red) uses the arrow keys. All code by me. Panel sprites by me. Baseball sprite by Scratch. Based off of Table Tennis. Invented in England. I couldn't find who the inventor was. PONG was the first adaptation of Table Tennis in video game form back in 1972 by Allan Alcorn
