Quite fiddly but at least controls feel tight. Graphics are clear and gameplay is clearly introduced. One thing I find a HUGE problem is that the red/green lights are all at the top of the screen. But if you're trying to do a pixel perfect landing you have to watch the pad and not the lights. When the landing pad is at the bottom of the screen, I can't really see the lights. Red/green is not a great colour scheme anyway, see http://gameaccessibilityguidelines.com/ensure-no-essential-information-is-conveyed-by-a-colour-alone/
Perhaps it would be better to supplement "red" lights with a universally recognised symbol (eg the hazard symbol, exclamation mark in a triangle?) or even to actually display it near the ship so it isn't necessary to look at the main instrument panel and away from the landing pad?
Music doesn't really the fit the game, the gameplay as a whole doesn't have much atmosphere or "personality" as someone else already said. So it's functional but not a lot of "fun"?
EDIT been trying to think what would make the game feel more fun!! The challenge atm mostly comes from flying the rocket through small gaps or even tunnels. Doing that pixel perfect is pretty dull. A greater variety of challenges would have helped. Perhaps consider introducing a moving obstacle rather than all the challenges being static?
