It's a fun game, but broken.. I'm really disappointed.. I spent cash on it and now none of the ad bonuses work. Then it started giving me an error and crashing when I tried to upgrade stuff, and now it 'optimized' to full screen and the whole bottom menu is just gone! The worst part is if I remove the app to fix that I will lose everything on it! If this gets fixed then it's a great game. But as it is, just disappointing and a waste of my money
