I get this was an early prototype, but it would have been cool to have some sort of objective or score to keep and a way to refuel or something, right now you've basically got your character controller (which I like the feel of btw!) and that's about it. Also would be good if you had some closer stars or something in the background moving in parallax when you move, when you're in the middle of nowhere it's impossible to tell when you're moving. Would like to see this when it is a bit more fleshed out. Good luck!
