Just to clarify a bit, from memory I saw 13 puzzles that relied on sound, there are 600 puzzles in the game, you only need to beat about 250-300 (Could be less) of them to start the end game part.<p>So you can definitely finish the game without sound, but if you&#x27;re a perfectionist aiming for 100% you&#x27;ll need to resort to outside help, which does suck.<p>The puzzles don&#x27;t even have a visual cue to let you know audio is important, so if you&#x27;re not expecting it these puzzles just seem unsolvable.<p>This and no colour blind support are probably the two biggest criticisms I have of the game.
