3 issues/bugs I found so far.
1. In demo area, when interacting with a something too fast after loading a save, game gives an error(I think it was about missing a file).
2. After losing all sanity, the give up button appears but can never be used.
3. Exiting the occult(area) does not work due to a missing audio file.
Edit: by occult(area), I mean area in the first picture on the game's itch.io page.
