Where can I find the save data?
I don't know if you've already searched for it, but this is the path in Windows (At least in my case):
C:\Users\user\AppData\Roaming\DigitalTamers02
(I think the 1st or 2nd "User" would have a different username if you have it configured) the AppData options are hidden by default I think, in the file explorer look for the "View" option, click on it and check the "hidden items" box (Text translated from Spanish) with Google Translate
C:\Users\user\AppData\Roaming\DigitalTamers02
