WOW! this is an incredible game!
How many years did it take you to make this?! You know what? If i were you I would put this game on sale, hell, I would buy, I mean whats better than a side-scrolling action shooter like this, I gotta play it evrytime I have free time, you have made NG the best game place ever!
Improvements for #2:
1) Make a boss meter scale to tell how much health he has.
2) Make the missles two times stringer when you have maximum missles and you pick up an <M>.
3) Add a better weapon system, I always graba green when I am going for a blue.
Tip to reader: Get the blue gun, it can wipe out enenies so easilly!
Another tip, how generous of me lol: The blue gun works best with a mx missle amount, so dont feel down if the gun doesn't treat you right!
