Blah! Not good!(no offense, please!)

No offense, but this wasn't good at all. First of all, the controls are backwards(What???). You can win by only shooting 1 bullet. And then the enemies don't attack. The bullets are too big and move WAAAAAAAAAAAAAAAAAAAAAAAAAAYYY too slow. The tanks dont blow up they dissappear into thin air. No offense please! I'm just suggesting that you improve this game. Oh and what is that thing in the sky?

EDIT: You can win by doing nothing.
