@Zark Might want to give this one a miss until you approach it alone then. Btw check out https://www.backloggd.com/games/the-looker/ after you two finish The Witness, pretty funny short parody

@Zark If you both pay attention to the story beats in between the puzzles you'd be able to swap off just fine. It's not like the Witness though - the story is a major part of the game and imo fantastic so ignoring it would be a shame. There's also lots of text logs to read between puzzles but all of Alexandra's time capsules are voiced at least (if you and your friend both reading logs would be too much of a hassle)
