I Wanna Be The Guy was released in 2007 by indie developer Michael O'Reilly, known as Kayin, as a free Windows platformer that parodied classic 8-bit games with deliberately unfair level design. Dying hundreds of times is part of the design, so its death and game over stings became inseparable from rage-game culture. As Let's Plays and fail compilations exploded on YouTube in the late 2000s and early 2010s, the jingle spread as shorthand for brutal, funny failure and editors still reach for it whenever a clip needs an instant, retro-flavored lose signal.
