This is coming a bit later than intended, but finally got the new sounds assets integrated.
Mad props to Petriform for another batch of amazing music and sfx!

• Fixed odd issue where the final door puzzle was secretly remaining open in a background layer if user returned to Main Menu from the victory credits screen
• Added victory reprisal music upon completing "Final Door" puzzle
• Added music box music that plays upon examining the music box artifact
• Added door creak sfx when changing game stages
• Added whispers sfx that plays upon opening any of the "face" views
• Added "unfurling scroll" sfx that plays upon examining any paper artifacts
• Added "misc items" sfx that plays upon examining many of the other objects

I'd still like to add some BookView UI feedback sfx, but that'll have to wait till next update
