Great game. But needs a level selecter/continue button. Also, difficulty isn't linear. 10 is much harder than 11 or 12. More programming space and a bigger list of objectives would be nice.
Oh, also really needs some badges and a card.
Not bad at all, especially if it's your first game. IMHO, color isn't a necessity, but a little bit more variation in gameplay as your score increases would have helped greatly. Still, much better than some of the stuff you see on the front page (*cough*laststand2*cough*)
