This is a two player game. The player on the left uses the 'w' key to move the paddle up and the 's' key to move the paddle down. The player on the right uses the 'up arrow' to move up and the 'down arrow' to move down. The first player to reach a score of 11, wins.
Post a comment to let me know what you think. Try modifying the game, make it easier, harder, make the ball/paddles move slower, faster, add obstacles, change the length of the paddles, the size of the ball, allow players to catch the ball and then release it, add extra levels of difficulty or whatever else you can think of.
