Rubik's Save Theory

@todo list:

• reference cube in many places like first bd/ending etc
• explain why ending cube is solved but you get devil and it breaks
• explain 4th wall break with save files (x spin is playing on timeline, y spin is swapping saves)
  • tie to konpeki jailbreak with shuffled floppy disk icons
• discuss in-memory values that carry over
  • playing birds in rogue ending path makes them play in hanako path in jungle
  • brooms in hidden broom closets can be synchronized
  • more
• etc
