First of all on my brand new iPhone 6s I have a bunch of memory available and when I change my place to fight a boss it shuts the game down. Another thing is it needs better graphics and more point to it. Its a great role play game but for those people that dont like to role play there should be a point. You should also add breeding to make pups to help you hunt and gather exp. Overall though its a great game. -Your Boi
