I patched the issue, the Boil room angel was bugged, and several other things where not working, but I quickly patched it. thanks for your reply~
Those are also my fav monster bois c:
i finally got to 15 teeth and the little black ghost spawned into a fight room, unkillable so I couldnt progress through the door, after attacking him for long enough my character started walking in random directions on his own, truly a sad day, I didnt want to hit the lil guy either... weird stuff... I'ma try to get endings again later.
