Player 1 uses the "w" and "s" keys to move the paddle on the left side of the screen up and down. Player 2 uses the "up" and "down" arrow keys to move the paddle on the right side of the screen. As the players continue to hit the ball, the ball moves faster. When the ball goes out on a player's side, the other play earns a point. The ball spawns in the middle of the stage and starts at the initial speed again. The game is over when one player earns 20 points.
Inspired the original Pong game.
