For the 2012 video game:
Many are documented on this wiki page.
- Silent Hill is referenced pervasively in everything, from the theme and feel to the aesthetics and gameplay mechanics, and even inventory sound effects. Slightly subtler ones can be found to Twin Peaks and its rogues' gallery of dream sequence characters, particularly its dancing midget, imitated by the old man.
- The game available for the GameJoy device is Soul Brothers, another Superflat game.
- "...got yourself a gun... got yourself a gun..."
- Chuck the Plant makes an appearance.
- The main character first appears in a heavily curtained area and has to drink coffee to proceed.
- "Blacker than a moonless night, hotter and more bitter than Hell itself... That is coffee."
