did my run, and got stuck before the bannister, so i tried everything i found and then read Tornadobomber tuto, so i did something like
Butt-plug, jelly dildo, door, phone book, phone, move carpet, torture horse, Pecan, Raleigh,Beelzebub, torture horse, bannister, Cyprus, Beelzebub.
and i realised i didn't need to take beelzebub in full to reach the ending, this is probably unintended, which is why i'm reporting it here
