Solving the duck-rabbit puzzle in Animal Well gave me such chills. In the beginning of the game the player comes across a room with a duck that quacks at you when you walk by. In a distant corner of the world there's a picture of a duck-rabbit with a passcode. When you enter the passcode in front of the duck, it transforms into a rabbit and warps away through a portal that appears for a brief moment while a spooky sound effect plays.
