On pc? You can just copy saves and put them in other holder. When you download a new version, just put copyrighted saves in game's holder saves.
If on Android, just download new version and done. No need to copy saves or something like that.
Hello my dear comrade.
I downloaded the game according to the instructions that you posted under one comment, but I have two problems:
1. An error occurs after trying to save.
2. The game crashes after a while. Either it is due to optimization or it is due to my weak phone (Redmi 9C). If this is due to optimization, then could you optimize this game for this particular phone? Forgive my selfishness, but I really want to play this game.
