Change Square
Calm down, focus and look carefully at the center of the screen. No. This is not meditation. This is the main action that you will perform while playing this game. All you will see is a large square and a small ball heading towards it. Your task is to click on the screen and, thereby, changing the color of the square, to ensure that both the square and the ball are of the same color. The task is not easy, but quite doable. All that is needed for its implementation is not to rush and carefully perform each action. Then you can get good results!
