If you had asked me last week I would have given 4 stars. Developing a game on this level is complicated and has kinks. That being said, the last couple of updates had some glitches. I did contact support through the game and they helped me very quickly. Since I updated it on 12/1, I have been unable to load the game. First, I got a message that said that I needed to clear my cache, which I did. Then I got a message saying there was a bug in the game. No help from support this time.
