Had an interesting experience with this one. Played through it once normally, thought it was cool, decided to try and play it again. This time I wanted to try and get to the end but not have to sit through the whole creepy section on every death, so I went into %appdata% to try and find the user data and delete it so the game would start normally. I could not find the data. At the time I thought you used some insane deep Godot trick to store the files somewhere besides Appdata, and I decided I had been defeated and moved on to play some other jam games.
Revisited this after the voting period ended, decided to decompile the game to see what exactly you did. As it turns out, the Appdata folders of your project and my project had the exact same name: "SKG Jam". Lo and behold, file0.txt was sitting in my own project's user data folder, hiding right under my nose the whole time.
