Needs work. A lot of work.
Well if anything you probebley shouldent do this at all. For a first try you didint do to bad, but you didint take the time to really add anything. For one there is no story, what space shooter that is actually fun and plays well, dosent have a story? It also dosent seem to have a highscores table which would be the purpose of this game. Anyway this is a very average to below average game. Just put in more effort next time.
