WASTE OF MONEY $4.99 paid to get rid of commercials. Stupid me. I find myself picking this game up to play wondering what will be next. Deals are sporadic and not worth it. Glad I only wasted $4.99 because this is the longest non challenging waste of a game.This is the game that never ends, it goes on and on... with no challenge. DON'T WASTE YOUR MONEY. Now I have gotten to the point where there is nothing left to upgrade and absolutely nothing else to do. There is an empty room on the top left.
