This game started out great, it really did, it was fun and looked like it had a nice charm to it.
But by the fifth day, the swarm of zombies and lack of possible upgrades made it too annoying and aggravating to play, MAINLY BECAUSE YOU EARN NO MONEY IF YOU DIE!!!
I get dying many times, that's acceptable in a game, but the fact that you earn no money by doing so, and farming the same damn level with the same annoying ass zombies isn't fun to do. maybe if you did earn money to buy better weapons or armor, it would be acceptable, but it's not.
This game seriously just isn't fun after the first few levels.
