We strongly recommand to shut down the Steam Cloud of Volcano Princess.

Because a bug that may break the savedata because of an error during Volcano Princess syn progress of Steam Cloud, especially for the ones who played the Demo version.
The devs are still looking for a way to fix it, but for now we strongly recommand you to follow the instructions before you start the game:
【But if you already started game and the savedata works well, don't do this!】

1- Uninstall the DEMO version (if any)
2- Turn off the Steam Cloud function

Library => right click Volcano Princess => Properties => General => Cancel the 3rd tick (cloud archive)

Please copy the savedata with physical devices if you need to move to another PC.
