画面をタップしてオブジェクトを落下させます。タワーが倒れた場合、ゲームオーバーです。
To build the tallest tower, you have to stack shapes on top of each other. Touch the screen to make the square that moves left and right in the upper corner of the screen fall. If the tower falls, it's game over. That's why you need to determine the place where you will drop the land well.
