Waiting Comments))) I think its be good project. In future i create many quests and ships. Its be like TDS Freelancer.
I like the music, but did you write it?
I would change controles, because you cant shoot in the oposite direction to your movement. I would make ships bigger, add zoom, put planet and non coliding object on diferent layer with paralax efect so player will not get confused ( like i ).
good luck
