You have to stop the ball from touching the red line, instead you have to make it bounce back by hitting it with the green paddle. To control the paddle hover your mouse left to right or right to left. Don't get shocked if the background has changed, the background will change in every 5 scores you get, meaning you are reaching the other level. The background will change four times meaning you have to get 20 scores to win the game, once you get 20 scores the game will stop, to replay, press the green flag.
Comment how many scores you get, and if you get 20 scores, you'd better comment below!!
