This is delightful :D You're obviously enjoying this a lot and I'm so happy!! *keeps count of how many times the game calls out Yuu* (I wouldn't be safe either if I played, I can already tell).

And re: the ghost, supernatural and several other details you mentioned, well! People have dug up an alternate, unofficial/unreleased ending from the game files that deals with that. I found it oddly disturbing myself, though in all honesty it isn't that bad. Look for "cult ending" on youtube if you wanna see.
