I see we had a similar idea :)
Looks very clean, I like the ship's trail and look of the planets. It was a bit hard though. Even level 1 took me a while to complete so maybe some easier levels before could be nice. I also wish we could steer left or right very slightly while flying so we wouldn't need to be as precise when detaching from an orbit.
Got a time of 3:42. I might come back later to try and get the high score!
