OneShot is an indie puzzle adventure developed by FutureCat Games, first released in 2014 and expanded in a later commercial version. The game follows Niko, a childlike traveler carrying a lightbulb through a dying world that includes the Refuge, and it became known for breaking the fourth wall with its players. Short cues from the game later circulated on soundboards and in fan edits, where this square death effect found a second life as a quick, recognisable signal for an abrupt in-game failure.
