Visual novels often save data in a local AppData folder. If you update to a newer version later, your saves from 0.6 may or may not be compatible depending on how much the game engine has changed. A Safety Note:

Once extracted, look for an executable file (usually ProjektPassion.exe ) inside the folder to start the game.

It looks like you’ve shared a filename——which typically refers to a downloadable build of an adult visual novel or indie game called Projekt Passion .
