Deniam what do i need to do to lets say i wanna move the games old file to a new hardware
Depends on your device:
If you're on PC, then go to "C:\Users\[USER]\AppData\Roaming\RenPy\WorldTamer-1695047755" and transfer the files inside to the same location in the new device
If you're on Android, Web, or don't want to look for files, then you can use the in-game feature called "Download and Upload Sync" They can be found in the save/load settings.
Click "Upload sync", save the code, run the game on the new device, click "download sync", input the code, and the saves will transfer.
