How do I update the game on pc? If I need to reinstall the game, can I transfer saves from an older version?
All you have to do is download the new version an unzip the folder and launch with the executable in the new folder the save file is in %AppData% which is not affected by simply changing the root directory of the game most if not all ren'py games save to the directory C:\Users\YourUserName\AppData\Roaming
this games saves are in C:\Users\YourUserName\AppData\Roaming\RenPy\Testgame-1635123618.
but like I said you should not have to mess with the saves I updated just fine!
Hope this helps
