Low Optimization.

Hello! Today, me and my friend, update version to 0.15.0 build 1. And we are very disappointed with your optimization on our phones . Approximately , we often change the FPS rate ( 25-27 ) .We are clear RAM. It is very difficult to play. I wanted to ask you, optimize the game, please. Thanks for your support.

P.S: Our phone is Lenovo A7000.
