This game was rather nice. Towards the end, say levels 25 and on, the enemies developed a certain bit of invincibility. I had to shower them in the Final Blast weapon for them to die. This of course, resulted in me having an accuracy of 117%. I'm not sure what's wrong, perhaps you've run out of variables or something, I don't know. I know starcraft does the same.

but wtf, i was using rapidcannon or whatever, the second to last one, on the 23rd level, and none of my shots were missing (well maybe a couple) and i was still being completely over run with guys. i played 4 times, and thats what happened every single time. i would loose right before i could afford the last cannon :[

But it needs work; the final weapon needs more range, and what the dude prior to me said. Where did you get the music from?

this is my new favorite like, bunker shooter game. the music is cool and when you get up to the autopulse gun its like a huge battle going on. and i was on level 22, and all i needed to do was finish that level and i could buy the last gun and mozilla firefox fakking crashed.

A decent defence game, but way to easy. I got to the point where i could buy the ultimate weapon without buying any of the other weapons or taking damage. And the color green you used hurt my eyes. WAY to bright!
Try making the game harder, and maybe add some structures you can buy.
Other wise pretty good, and worth playing.
