REALLY NICE GAME! But one flaw.
I love the game style, i love crazy shootemup. Graphics were good for the type of game(defence). Sound got a little repetitive later, violence is uncontestedly good, interactivity is limited because of the style, but thats OK. Humor, well, running around with a Jackhammer mowing down everything in sight is amusing. One flaw though. Once I got the 1200 dolla machine gun, I saved up until i got 3k, got the laser, then got Overkill. Laser + Overkill + 6 basic zombies = one very rich bastard. I got 6k xp in one shot(I don't get the math :/). Fix that or remove the overkill and the game is pretty challenging.
