The game originally renders at 640x432 which is then presented letterboxed at 640x480. Enabling this option removes the forced letterbox effect, so that the game fits better on screens with an aspect ratio wider than 4:3.
The game will include in-jokes and references to past adventure games, in the form of both dialogues and objects. There is a game achievement that can be obtained only if the in-jokes option is switched on.
