The game recognizes at least two different cheat codes with varying effects:
The code is . On the final press of , the game unpauses and plays a sound to confirm entry.
Doing so causes the Even Care music to stop playing, and makes the exit to Even Care lead to the Newmaker Plane. Additionally, the transitions in Even Care go from being fade-to-white, to being fade-to-black, and take much longer than usual. This effect does not persist when Even Care is revisited later.
This code is revealed in Petscop 15, and allows the current player to see the textures the game is using, as well as drawing on them with a pencil cursor.
