Good game with small flaws

I find this game all in all very well done. You can play the game very well, even without real money.

There are very many plus points that I did not want to mention here. The game would have 5+ star deserves, if it were not for a few blemishes that are crucial for me in part:

1. The game crashes but from frequently.
2. Adding friends is not sufficiently described or load the Friends list takes forever.
3. The most fatal flaw of the game is that the scores are not transmitted via Facebook or Game Center (Iphone / Ipad). It so happens that I go the game can not play, because I have my account on the iPad and iPhone, the game starts again completely from scratch, although I am greeted with my name on the Game Center in the game.

As I said, the game is great ... but it is not 5 star.
