YMMV / Do Us Part

• Complete Monster: Lord Vollo is Margerita's husband who is revealed to have tortured and murdered his prior wives. Among his victims were Margerita's sisters Luisa and Carlotta, the latter of whom he manipulated their father into letting him marry with the father's debt. Claiming at least six wives, Vollo would chain them up and kill them in his Torture Cellar, indicated to be as sacrifices to demonic forces, and also imprisoned a talking cat to prevent it from stopping his murders.
• That One Puzzle: The desk puzzle, one of the first puzzles it is possible to do, is notable for tripping up some players. You have to find a 2-digit code, but the only hint you are given is an easily-missable pile of books to the right of the desk which bring up a book about “the principles of addition”; from there, you are supposed to realize that you need to add up the numbers in the other books. As such, some players simply brute-forced the password instead.
