the creature you play as in remembered is called room hes from the channel _boisvert, the other characters on the channel are called Ouriel (called antlers guy by film theory), dogtooth, the puppet god, the angel and the coplex (might be a form of the puppet god)
the song "comatose" is based off of the boiled one, what the boiled one does is that once you see the boiled one you'll always see the boiled one and no one can see the boiled one but you
underrated video! hope you get more traction. you got some good content potential!! (side note that secret song at the end of the credits was bugged for you, its not that bad but if you play it not in full screen or in a latter patch it would probably be a better experience)
Loved that video man, one of the best mods for sure. I wanted to recommend you another horror mod called Dead Air, it's like 15 minutes long and it has 1 secret song. Definitely my favorite mod in fnf, hope you enjoy it too.
