About this game

In this game there is a square and a ball in the square. The ball will move through the square and collide with the edges of the square. But the square can flash when you touch it. You need to touch the square whenever the ball bounces off the edge of the square and then the ball can bounce and continue playing. If you miss the moment and the edges will flash sooner or later from the touch of the ball, the game is over.
