To elaborate on what was said in other replies to this comment. Jonathan Blow has said previously that he got around some of the puzzles being fiendishly hard by not requiring all of them to be completed to get to the end of the game. He didn&#x27;t want somebody to get stuck on one puzzle and then not be able to see the rest of the game over it, so you should be able to complete the vast majority of the game including the ending just fine without those audio based puzzles.
