A bait-and-switch prank game of unknown origin, which became viral during late 2000s.
It is essentially a maze game that looks normal at first, until you reach the last level, which has been made near impossible. Before that, touching the walls simply restarts the level, but when you reach the narrow part and hit the walls, an image of Regan Macneil from The Exorcist suddenly appears.
Most (in)famously known from a Saturday Night Live sketch involving a man who got so startled by the jumpscare that he literally punched his computer Screen all the way through.
