Downloaded and started playing and it was going great even Earned and claimed my first pet. Then came back to play next day and couldn't sign in with facebook. Tried and tried and it keeps sa_img there was an error signing in please try again later. Needless to say I have completely lost all of my progress and all the rewards I have worked hard for to get. And as for only 50 energy there should not be any energy needed to play this game should be unlimited So disappointed and disgusted
