A key puzzle in the attic involves a music box. You'll typically find a broken music box and need to locate its missing parts, often a winding key or a specific cylinder. These parts are usually scattered throughout the attic, requiring you to explore various nooks and crannies, often in areas patrolled by the Shadow Figure. Each part might be hidden behind a stack of boxes or on a high shelf, necessitating some climbing or object manipulation.
Once you have all the parts, return to the music box and interact with it to repair it. Playing the music box will often trigger a significant narrative event or open a previously inaccessible path. The melody of the music box can also temporarily deter the Shadow Figure or create a safe zone, allowing you to progress without immediate threat. This puzzle is a crucial step towards finding the final memory and understanding the game's deeper themes.
