I enjoyed the presentation of the game. The music was chill but driving and the graphics were simple, yet effective.
I would maybe implement a tiny bit of drag for the ship, so
1. you don't go flying off every time you wanna turn around and
2. the "best" play is always to just keep floating and wait for something to perfectly cross your path, since it doesn't cost you any fuel to just wait - maybe some sort of time constraint would also fulfill this problem, though.
Overall I enjoyed the concept, great effort :)
