Bests & Worsts Reviews from Amazon

A challenging game, but I've enjoyed playing it. I worked very hard to get to level 110 only to have all my progress disappear. Another reviewer who had the same problem was told logging into Facebook would prevent this, but it does me no good now. Besides, I don't want to have to log into Facebook to play a game. Since I have no intention of starting over, this app will be deleted. I am extremely disappointed as I wanted to see what was waiting for me at the end of the game.
