A simple but challenging game! There is a ball moving inside a circle and you have to keep the ball inside this circle. The circle has no physical border, so you have to move the platform that you control so the ball hit this platform whenever it reaches the borders and keep the ball moving inside the circle. If you fail to move the platform in time or don’t position it correctly, then the ball will exit the circle and you will lose.
