Very fun game. Gaming 4/5 but giving 2 because there's no saving data feature, google play sign in, google play achievements. It's no fun if you can't uninstall and then again install after some time and get to where you left it. I probably won't install it again after uninstalling because I've to play from the beginning. And it's no fun that you can't compare with your friends online through Google play games. And there's a slight bug in my daily online challenges. It doesn't save my upgrades
