Oftentimes the "player" will enter a command that is beyond the actual "game" but will be shown as an actual action.
Prime examples include:
What is more particular about this is that the characters in the game themselves are not above this tomfoolery either, and will go outside of the game's boundary in order to solve some Weird puzzle shit or get through some of the really boring and useless parts of the game.
In Homestuck, this does not particularly apply since the setting is mostly on present-day Earth, where the typical outside actions would exist. Secondly, Sburb is an in-game example but that also is controlled by an in-game character, so... Yeah... The game hasn't been "paused", but there has been one GAME OVER scenario in Homestuck, followed by retcon mechanics modifying the meta-narrative.
