Yes, I do realise that there's plenty of flaws. However keep in mind that this was done in less than a week with only basic programming knowledge. Flash managed to screw up the graphics somehow when rescaled, which was a pity. Thanks for the feedback though.
I lol'd, when every programming was done, i tested the movie. What happend? The enemies came flying normal, but then they shot a missile and they suddenly exploded. There was also a white missile of mine in front of them, even if i hadn't shot any missiles.
