I actually managed to connect my account to Google play games, and this allowed me to retrieve all of my data when I had to factory restart my phone. Although I think this might be limited to android users, but I don't know.
I Would love to see moga compatibility come to pixel gun. I honestly think this feature alone will make the game even better than it already is. What does everyone else think?
(And in case you don't know what a Moga is, here are some examples.)
