For me this was one the best games on the Atari ST. I whole planetary system to explore. The Graphics where basic polygon filled with sparse items in them but back then who cared in 1990 this was the open world game you wanted. The basic story was you where to stop a comet from destroying a planet and you only had a certain amount of time to complete. The great thing is that you dont have to destroy the comet there where other options. The graphics where simple, sound effects sparse frame rate was low but at the time you did not care . I remember also there was a house on a moon i think that was the creators house with a terminal you could do crazy things in the game world. These days the game may be too simple and boring but i would still love to be able to explore that system again.
