Hi, thanks so much for playing! The level 1 tape is the piece of music (with piano and cello) that plays after completing the puzzle, unfortunately the game is missing some assets like tape labels which make it easier to understand what each tape is - apologies for the confusion! We are aware of a few bugs in the current build that make it difficult to progress past Level 5 and hear the 5th tape play. To provide context for the currently inaccessible components, we have uploaded the missing assets on the game's main page (https://mvs-music.itch.io/repair-and-rewind) and music on my website (https://www.mvs-music.com/videogamemusic/repair-rewind). And yes the settings menu doesn't work...yet! Hope that helps!
