Green Circles

"Our ball in the Green Circles game has gotten itself into a very dangerous situation, as it involves thirty challenging levels that must be cleared to escape. Each level consists of two rotating circles with an empty space. There are sharp spikes inside one of the circles. If the ball collides with them, the game is over. The circles are constantly spinning; you just need to press the ball for a jump, and ideally twice, so the jump reaches the desired height and the ball avoids hitting the tip of the spike."
