Hey, it's fun, I like to watch the playthroughs after I played through the game. Did that with Aquaria, .though to be fair I had some problems finishing it because of the bosses and my very poor hand-eye coordiantion, so I just kept watching, but Aquaria is a trully impressive game. I actually did watch the playthroughs for Silver Lining too. there are a couple floating on youtube.
Just a few comments on these two parts from me (don't worry I will not be harassing you with comments on every part you release

But I will enjoy them)
Actually I am discovering with your video some things that I have missed, like the runes, I really had not seen them or paid attention to that at first. There will be plenty of such things, I'm sure. And you sure know how to analyse. And yea your theores, especially at the beginning of part 2 are interesting for sure, but then, anything can happen in these crazy lands.
Watched both 2 and 3 found myself interacting with what you're saying and nodding when I agree with your thinking. You did miss a few things in the town upon your first visit,. but you'll figure it out sooner or later; also at some point you just know you are missing something.
It's just that.. entering the same town months after the previous part always strikes me like that: you're inebriated and excited and notice things which you kind of expect to notice, or where you expect things to perhaps change (well most of the time, you really suprised me with these runes), which causes you to miss, at first, some of the elements that later seem so obvious. the game surprises you yet again with something you did not expect perhaps.
Can't wait to hear your commentary on when you see the rest of the Isles of Mist and other isles and some things will become even clearer. Also, love the title to part 3...oh, just you wait until you learn everything and see all cutscenes.
In part three @ Hahah at 2:48,; I did the very same thing, just a tad later when I THOUGHT I had the thing I needed.
-@5:35 I do think the voice sounds familiar but I can't put a finger to it either, although it seems like a voice of a a well, street flower vendor/ other lady vendor from some period piece to be honest; it;s just the kind of voice you would hear in a period piece.
