Super Mario Consequences is a partial re-make of World 1-1 from Super Mario Bros, but with a twist. Goombas in this game are completely harmless but will cause a bloody splatter when stomped. Killing goombas or koopas also causes police goombas to appear from the left side of the screen which will chase the player and attempt to arrest him. Getting arrested for murder will result in a jail sentence of 20 years real-time, during which the player can't do anything but watch the timer count down.
The point of the game is to call attention to the fact that players never expect there to be serious consequences for killing things within a game world, and that enemy deaths are commonly used as the strongest feedback mechanism in games.
