Flying Ball Wall Bouncing

Flying ball wall bouncing is a fun infinite simple game where a ball bounces off both sides of the screen back and forward, but the ball has to hit a certain part of the wall that are highlighted green to continue bouncing off the walls. Your mission is to control how high or low the ball is on the screen to make sure the ball will hit the green part of the wall that will constantly change as you play. Your reward for each time you successfully hit the green part of a wall is a single point that will add to a counter at the top of your screen. Try to get the highest score of points out of all your friends! :)
