The Sojourn

Hi all

We have a full walkthrough that shows all merit locations. There are 46 merits in total. The majority of the puzzles you play have merits in them.

It’s a long video, so here are the timestamps:

There are 46 merits in total. You can gain at least 42 of them by completing a second challenge in most of the last 20+ challenges (I say "most" because some of the final challenges do not offer a merit second challenge). There are also four side-challenges (not including the two before you enter the building in the beginning of the final journey (Vision or whatever)) that you will encounter (these are not needed to be completed to progress through the actual levels of the game to make it to finish the sojourn) that will give you three or four merits. I say "three or four" because there was a pair of side-challenges of which I completed both, but only received one merit for one of the challenges, so I imagined they were collected in pairs until I encountered the final two side-challneges (which appear just before the entrance to the final garden) and each of these gave me a merit to total two merits for this pair, so the earlier pair may have been glitched. Either way, you should be able to collect at least 42 merits before the final garden by completing the second challenges in levels that unlock a scroll after making it to the final/exit platform, in which you will be shown all merits that you have collected sitting on pedastels, plus the opportunity to re-visit any you have missed, which should be glowing atop their pedastels (the other, complete, merits will not glow but you can again read what the merit said one you collected it by standing in front of it an pressing X for Read). I came upon four new merit opportunities in the final garden. These could be brand new merits? I don't know. But most of the ones I visited from the garden contained an exit area column-of light pillar platform as if I had already been there, so I just assumed I forgot to collect the merit in that past level as I climbed my way to this garden. So it looks like you can collect passed and/or ignored/forgotten merits from this final garden. I just completed solving my final four for a total of 46 merits to unlock the beauty of the final garden and this achieve, and I'm about to collect Eternity (I hope) achieve by "finishing my sojourn."
Good luck!
