It is about the lonely trip of a space ship driven by gravity field in the vast cosmos where the ship would face blackholes, enemies and resource mines.
The ship holds the engine to generate gravity field to make itself move. The generated gravity field is designed to be equal to an object with a great mass and a certain distance away. The job of the driver is to decide the status of the gravity field, i.e. on or off, and the location that the generated gravity field in observation. The engine is powerful enough, as being able to generate the gravity field times from the blackhole.
... All above are the scenario of the designed game background. Take it easy, you are to design the path of the space ship to get resources, evade enemies and blackholes, with all you could make use of is only the gravity field generator.
