The save game is located at C:\Users\{USERNAME}\AppData\LocalLow\Tulpar Games\Taora Beginning\Saves
Here you will find your save data. You can change the file extension from .tsg to something like .back1 to create a new save file, then start a new game, to switch back, reverse the process.
To have it sync between PC’s, setup a cloud program like Google Drive to backup this file in this location on both computers. Personally, since both PC’s are one the same network, my AppData folder for both computers is shared to the other PC on the network, I just copy and paste to the other computer when done playing. The save file is very small.
Hope this helps someone!
