Gamemun was a screamer flash game created by Nickket on 2006, however, the creator appears to be Danish.
The screamer attempts to fool people into thinking they're going to play an actual game. A loading screen is shown, followed by a screen with options to choose "1 Player" or "2 Players." After either one is chosen, a female face with white lipstick and red eyes is seen and zoomed in for one time, along with a stretched crying sound effect. The sound will continue to play continuously until the player closes the game.
NOTE: The following game contains a screamer.
