Great graphics, Great idea. Horrible balance.
The difficulty made me stop about 7 days in, I just could not hit that many zombies that fast. I understand that using the safe zone is supposed to be a way to stomp and kill but after 2 days of doing that I made almost no progress as I killed all the zombies and didn't get to collect anything. If the makers of this game ever happen to read this review just two things I would change. Make it so you gather a certain amount of stuff to advance instead of killing all the zombies, and tune the difficulty back or make weapons stronger.
