I didn't even play the game and got already a bug.
The game freezed after the first loading screen than I tried to restart the game (without closing) and got a huge graphic bug.
I am not sure if my phone is to weak for this game but when the zen logo appeared I got no lags and no graphic bugs.
The first time I started the game without a freeze but the graphic bug was already there.

I took some screenshots
