WD for up and down on left and Up and Down arrow keys for the right side. Press space to release the ball. Sometimes it glitches - I honestly have no idea why. You can play regular or challenge level, challenge has a smaller ball and paddles, and the ball moves a bit faster. Should I add inverted controls on challenge level? If you notice any bugs please let me know. Once one of the players gets to 11 points and wins by two (11 to 9, not 11 to 10) the game is over. Click the green flag to try again.
Made this with my own ideas, just upgrading a class project.
