Very nice little atmospheric game! The controls were a bit tricky at first, but I think this because I did not notice I was accelerating and decelarating. Maybe if there were some stars in the background I could see that I was still moving and more easily gauge what my speed is. Also some effect that shows that my engine is working would have been helpful I think. Once I played a bit I got the hang of the controls though and it felt great!
Other than that I think the atmosphere was really well done. The stars looked big and dounting, as they should. The planets small, but pretty. Sometimes it was a bit hard to take off from a planet once I crashed, but that was a minor thing.
Great submission! I enjoyed it :D
