good concept but you should work on it much much more. u need prices when scrolling over the upgrades, a different picture for each of the items that you pick up to define what they are. you don't need a bunch of good graphics and complicated codes to make the game good but just some added clearness helps for a good start
this is a fast paced game that i think a TON of people will enjoy....it gets progresivilly harder...and ur flying a missle through a tube which is strangly addicting.
