I didn’t even have time to try the game before I encountered an error (possibly).
In the mobile version, if you access the settings menu from the main menu on your first login, you can’t exit that settings menu. The button is simply missing.
In the game, it seems there’s no “Back” button at all. As soon as you enter any menu, you can’t get out of it.
I understand that you always need to move forward and not look back, but... I think this is a different case...
