Bug – 2012 Zombies vs Aliens Review

Very cool game concept... Some strategy and different units makes game fun HOWEVER sadly for me I can't use different units I can use it level 1 first unit!!!! I have a bug where every time I click on an upgrade my game freezes. I can't do anything except close and restart the app. How far do you think you can get in the game with just level 1 units? I have no idea but it is boring and I'm frankly not gonna keep trying :/ Patch bug
