I generally don't play games on Newgrounds for very long considering that many of them are a little boring after a while. This was not the case with this game. Great job man! Just one problem though, it seemed that the add zombies to army + and - were a little slow. I mean, I know that the thing will speed up if you hold it long enough but I found myself clicking as rapidly as I could because of the time it takes to reach the fastest speed of adding or removing zombies. Just a small problem, though. Doesn't take away from the game. Nonetheless, good job.
