You basically have to do nothing since it’s an optical illusion that only involves sight.
If you keep looking carefully, when you see it keep looping, it will look like you’re walking infinitely down the hallway, as if it never ends. TRY THIS: Try putting your hands on the sides of the screen when in full screen. It looks like you’re moving slow. Now try covering the middle of your screen. It looks like you’re moving very fast. This optical illusion involved no sprites, only a change in backdrops. #NoSpritesChallenge #BackdropsOnly #OpticalIllusions
