Pretty fun game.
This game was pretty good. Simple controls, simple buildings and fairly lenient on the difficulty. Only one problem, the game DESPERATELY needs a speed-up button. Not only do the zombies move fairly slow, they sometimes get confused and wander around back streets and crap, and all you can do is wait. The pace is fine for when you're building stuff, but when you don't have anything useful to build and are just waiting to clean up the rest of the zombies, it was got so dull that I started playing Solitaire just to wait for them to die.
Other than that, it was a pretty fun game, and I spent a good 3 hours or so enjoying it.
