The game turn me a scared...

The option to play in 3 modes is very cool!
Keep up the great work!

Lag city.

An entertaining time-waster until it starts to lag. Graphics are pretty lousy, but whatever, I can see past that if the game is fun enough. I realize this was not intended to be a Flash game, but you really should have optimized it for Flash if you were going to make a version for the internet. Anything to deal with the massive lag.

Also, for cod's sake, put in a dang pause button.

nice xD

nice game :P not awesome but cool one

This is great!

I REALLY loved it, it did get kinda laggy though when my gun upgraded. But it was still good.

good

but has problems. first it lags! second it has a tendency to have the zombie "dodge" the bullets. and thats about all the big ones.
One thing i would suggest is making a health bar.
other than that VERY GOOD!^^
