How do you save visual settings? Once I close the settings section then open it back up it kept checking the box I unchecked before. My game keeps crashing too :( (I'm on mobile)
You don't change visual settings - those were forced disabled but the dev for optimization purposes
As for crashes, the only workaround is to clear cache and hope it works
Another potential solution is to reinstall the game from the same APK file you first installed / updated - basically if you have, let's say 0.5.2.0.2 version installed and still have the APK file for that same version, trying to install that game again on top of the one you already have might help as well and you won't lose save data
