I'm enjoying the game. It's a very fun time waster. The reason for the 3 stars is the forced ads, they're just too much. I'll gladly watch ads for resources, and I'd be willing to pay for an ad free version, but if and until that happens I can't rate any higher. Edit: amended to 5 stars because option was added to remove all ads for a one time payment. All it needs now is cloud saves.
