I surely have missed some puzzles down the way during my journey. Since I'm not making a walkthrough, but rather telling a story of my adventures in Elsewhere, I'll leave the story as is. You need also to realize that I've shot it 2 days after its release so it would have been a huge task for me to understand all the intricacies of every puzzles in this age if I had pretended making a walkthrough out of this series of videos.
I've already shot an entire new chapter (Chapter 6) by finding out the missing pieces in the Faraway Islands area. And still... When you'll watch that specific chapter, it won't even be integrated inside the main storyline but as a digression. My journey is not perfect in terms of puzzle solving (I'm mostly referring to the logical / mathematical ones, too strenuous for my tastes). I decided to shoot the adventure nevertheless because of the numerous talks among explorers finding that the age was too huge, too difficult, too complex, not playable, not loadable, etc.
I'm sure people are enjoying the adventure so far & will enjoy what is still in reserve for them.
Storywise, the puzzle(s) I didn't solve correctly or even skipped in the Crescent Island surrounding area can be easily explained; I was not at ease in the Temple at all. I'm still quite frankly not at ease there at all. The terrible noise the green dots are making are driving me crazy. I find the location creepy & it involves a logical puzzle which is far from being my cup of tea.
For example, the puzzle of the Sliding Doors Island took me what... 20 minutes to figure it out. That's a puzzle fit for me! It's all based on observation skills and learning the behaviours of a given entity. Maybe some explorers will have hard time understanding that puzzle but will just go in the temple, look at the clues on the docks, go in the tunnel with the 8 barriers and say: "Oh! That's an easy one!".
I'd rather keep my journey as it is since it's depicting my reality, my understanding, my path to reach the ultimate goal of the age. You'll see that up until the very last puzzle, I'm doing it mostly all "wrong" according to the intended gameplay but all "right" according to my way of thinking, my way of playing.
If, on the other hand, someone is willing to solve & share the solution of this puzzle, I'll be pleased to know the solution but it won't change the current journey I'm sharing with all of you in anyway. It'll only affect my future gameplays. I would also be open to shoot additional video(s) once every missing pieces will be known, video(s) in the same vein as the Chapter 6 one. It would then consolidate the whole series.
