....which did you choose? Please don't say what happens after the choice as I'm going to play through again to see the other ending myself. I chose *not* to swap.

I'm going to guess the other ending doesn't warrant a whole playthrough but it will give me another reason to pick this up again later (the other being I want to see if those puzzles are easier the second time)

I swapped. About seeing the other ending I would to recall there is Youtube.
