According to Newton's third law of motion every action have an equal but opposite reaction. In this fun puzzle game you need to avoid the gravitational pull of planets and stay away from pesky comets that otherwise might block you from your objective.
You are the captain of a space ship that needs to destroy an alien space station. The thing is that planets have gravity that might change the trajectory of your bullet. To your help you have a number of satellites that contain a force field which also changes the trajectory of your bullet.
You need to carefully place these satellites around so that your bullet will hit the space station.
