Finally, the latest version has become free. But where did the saves from the previous version come from? Usually in every new version you always had to start from the beginning
The game engine(Ren'py) puts the saves in a seperate folder on your PC, so they persist even after removing the game and downloading a new version. While this is a great feature, you currently can't load old saves from older versions in Fattening Career, otherwise you don't get to see all the new content.
