In this game you will see some big balls with small balls as satellites rotating around them. As the big balls move and the satellites rotate around them, the satellites may crash into the sides of the play area. You can click the big ball and the satellites will reverse the direction of rotation. If you time your clicks carefully, you can avoid the satellites from crashing. In each level there will be a time limit, if you can survive through the time limit, you can advance to the next level. In each new level, the balls may move faster, or there may be more balls, or the satellites may move faster or move at a longer radius. In short the new levels will be more and more difficult. In you failed in a level, the game will be over and your score will be calculated based on the time you stayed in that level.
