Ratings and reviews

Its a good game. Fun to play. Expect it does not let you always go back to game when u push the retry button. It will go to the ad then go to the play store. So u lose all the time and all of the monsters u created because u have to restart the app. Alot of people feel like they r getting screwed over by this. This needs to be fix. Please and thank u

My game wouldnt save and every time I logged in I had to start over from the beginning, even though my account was linked. Tried uninstalling and reinstalling. Nothing seems to fix it.

App wants unnecessary access to things like phone call... I played this game for over a year before and there's no ********* reason for this download at risk... I wouldn't trust it anymore
