This was a lot longer than I expected it to be! Kudos on getting all this done solo. This definitely gave me a few genuine scares. I managed to get through the minigames (after some do overs. Including one time where the monster spawned right outside the start door) but I just wanted to add I really appreciate you adding the option to skip them regardless. I would've loved to see more of the story, just to understand what's going on more.
That menu music is incredibly familiar, did you pull it from something? I was thinking maybe Silent Hill, possibly specifically 3.
