How about when the game is installed through the itch desktop app? I have it installed there since the game can automatically update that way, and also wanna start from scratch to show it off to folks.
Nevermind, found it! This is for Windows 10: The itch desktop app seems to have its own folder under your Users folder. Go in there, then use the AppData>LocalLow>The Haunted PS1>HauntedDemoDisc2021 path.
