Copied from my other comment answering this:
If you still have access to it, sure - you can transfer your save data from your old game folder to your new machine :) From the Discord:
WHERE ARE SAVES LOCATED ON PC? PC > Local Disk (usually C:) > Users > USERNAME > AppData > Roaming > RenPy > CorruptedKingdoms-1547378918
WHERE ARE SAVES LOCATED ON MAC? ~/Library/RenPy/CorruptedKingdoms
WHERE ARE SAVES LOCATED ON LINUX?~/. renpy/CorruptedKingdoms/
WHERE ARE SAVES LOCATED ON ANDROID?Android/data/com.domain.corruptedkingdoms/saves
NOTE: If you're running Android 11+ then Google has hidden your data folder. To access it you need to connect your phone to your PC with a USB cable or use an app like Solid Explorer or X-Plore to give you access to the folder again.
