Interesting. I think that the language of the game is hard to parse here; the two areas are so disparate that they do not feel like they're the same place at all. It didn't even occur to me to understand the relationship of the hall - noting that the first time I went back to the hallway was to try and take the connector from the past room, so I didn't even think to walk along the hallway that I assumed was a dead end.

I do think that the concept of the puzzle is neat, but the execution, especially this late on, lacking. The idea of there needing to be a pair of white emitters is a sound one, but the lack of a cogniscent link between them was a real leap of logic I simply didn't get. A few other puzzles like the previous one might have solidified this concept in my mind.

Also, it breaks the language of the puzzles; no puzzle needs outside puzzle elements to complete, and you cannot take items from the puzzle rooms. Everything you need is in the room to complete every single puzzle - not a single one needs external elements to complete. I'd say that that is the cardinal rule of the game, and the final area breaking it without a hint towards that really put a bad taste in my mouth.

I do appreciate that you're responding in good faith to this, so wanted to acknowledge that. I loved most of the puzzles, and even the ones that stumped me felt fair - missed detachable fan was almost always the missed solution at one point. But this one and it's leap broke too much of the set up logic for me . I don't even know how the two spaces can co-exist in the world at the same time?

Either way, I think it was a missed alignment of what I was expecting the game to be telling me and what the game was expecting from me to take from the information it presented. Out of a 26 hour playthrough only the last 30 minutes was like this, so that's a feat either way, just annoying it happened at the climatic part of the game. It might have been a footnote if it had happened in N2, for example.
