Here is a lonely, weak and helpless ball in danger. You need to help him to reach the designated position to pass. Each level has two unclosed rotating circles. There are spikes in the circle. The game ended when the ball hit them. The circle is rotating. You can press the ball to jump for a period of time, preferably twice, so that the ball can reach the height required for jumping, and the ball will not fall on the tip of the needle.

Click the left button of the mouse to control the ball to jump. You can only click twice in a row at most, and the ball jumps twice. Be careful to avoid sharp thorns.
