Tomato Tomahto

Great Zooks! Space has been invaded by blood sucking vegetables! What ever should we do?.. .Hire a space vampire of course! Play as  S.A.P the biogenetic vampire and rid the planet of those pesky killer tomatoes! 

This is my first game made through game maker studio. It is a basic "asteroids"-like shooter game and pretty simple.  Any helpful comments and advice would be much appreciated. :)
