Thank you for the suggestion. We will definetly take everything you say into account. One thing that we have fixed is the zombies. We have improved their ai so they do not get stuck all the time and will probably not slow down the game too much as more zombies spawn. One thing that is supposed to happen is that zombies get stuck when they run into walls so that the other zombies can climb on top of them so eventually it would make a bridge to the player. Also the fact that you can build a wall all the way across the top of the map and no zombies can get you will be fixed as well. Thank you for all your feed back we will use it to improve this game.
