Hi,
I'm only doing my part, so that dev has more time and less worries and can be more productive when it comes to development of the game
As for transferring the save file, I don't think it's impossible, although no one has managed to do so or I don't know about it, the main problem is that Google has heavily restricted access to Android/Data folder since android 11 or 12, and that is exactly where the game and save data is stored, so until your phone is rooted, there's jo other way to transfer save file to PC
The discord "verification" takes place only on discord, you are supposed to input that code in the Verify channel, just as you would write a normal message, read the instructions again, just do as you're told, don't overthink, the task is that simple, just type the code and you'll be in!
Cheers
