Let's start with the obvious: These renders are gorgeous and, together with the stellar sound design and writing, build a wonderfully heavy, "larger-than-thou" athmosphere. This is really impressive.
I liked the choice of the more observational puzzles. Figuring out what exactly to look for and paying attention was really engaging without needing to understand some kind of arcane moon logic.
My only issue is with the navigation. At times, I felt disoriented because I did not know how far I have been spun, especially at the four way intersection. I also sometimes didn't find the correct hitbox that got me where I wanted to go; sometimes forward was at the upper end of the screen and at other times in the middle as one example.
These were many words to explain a rather small issue, so let me reiterate: This game was a real treat and I enjoyed it a lot.
