While I thought this game had promise, I hit a point where the game became unplayable. The game got stuck in a never ending loop during the first zombie attack of the game. The screen would flash back and forth between the people outside the gate and the attacking zombies. Trying to tap the skip button did absolutely nothing. I have closed the app to restart. I have uninstalled then reinstalled the app to only be stuck in the same place. What a waste of time to not even be able to play.
