Use the up, left, and right arrow keys to hit the ball into an opponent's square (the game allows you to hit the ball when it is touching you, but if it passes your center, it will be a "miss" and you will be out). Be attentive and have quick reflexes to get your opponents out and make it all the way to A! When you are in A, press the right arrow key to serve the ball.
This game is extremely advanced and took me a really long time to make, so I would appreciate it if you liked it, favorited it, and showed it to your friends. Please give me constructional criticism down in the comments below; I am grateful for all!
