Use to be great
This game use to be a great time killer. I haven't played it in a long time, and stumbled upon it today. The aiming has become terrible. I don't know if it's the zombies being faster or what, but I use to be able to play level after level without a problem and now I can't even kill the weak zombies on level one without them swarming my house. I'll aim right for the head and never get a hit, especially if they're right in front of my house and they get there within 3 or 4 seconds. Fast zombies are a welcome addition, but without the aiming, it just makes it annoyingly difficult to play.
