Okay, so in the second room of the first chapter (the one right after the kitchen), I can cheat by rotating the locked painting to the side with the q or e keys.
EDIT: Not only is it hard to open the treasure chest in the riddle room NVM, just need to turn riddle mode off, but the "friend"'s jumpscare genuinely got me!
ANOTHER EDIT: Turns out that tilting the painting is necessary, since I can't rotate it when the bottom two locks are on it!
