For those who may be unfamiliar, Animal Well is a game that combines elements of exploration, puzzle-solving, and platforming. Players take on the role of a character who must navigate through a mysterious world filled with strange creatures and obstacles.

At 60 FPS, it extends 30% further than intended. At 144 FPS, it can clip through walls, but if it hits an offscreen switch, the switch toggles before the yoyo visually returns, causing a state desync where pressure plates behave as XOR gates. One sequence of such desyncs unlocks a door to a room containing only a single, non-interactable pixel—which, upon inspection, is a minimap of the entire Animal Well map rotated 180 degrees.
