Metaphor Temple is a text adventure game that Finn plays on BMO in the episode "I Am a Sword." He plays it late at night to stay awake because he is afraid he might have another "scary guilt dream." Jake describes it as a "brainy, modern video game," and Finn considers it intense. It is played using a mouse, though Finn also had a keyboard plugged in, so it may also use that. Only two of the game's screens appear in the episode.
