It was, such, such, such a good game. At least for me, maybe because it's perfectly my personal preference.
I am only writing this much for to say how much I like this, and I am sure some things I said you already know.
First, the vibe is astonishing. The music, the art, and the narrative fits together seamlessly. I know it is a game mostly with puzzle, but I enjoy the part that is not the puzzle so much that I almost do not want to enter the puzzle. The hexagon wall, under the water environment, fish, blue lighting -- with the hand sitting on the chair, really build an otherworldly vibe for me, that I whole heartedly enjoy. With all of that, the narrative is very philosophical and contemplative, which I really love. The visual in puzzle does feels a bit out of place not gonna lie, but that might also be caused by the scene outside of puzzle feels way too good... the pixelated planet and how that ties up with the narrative in the space was really clever. I also really really like how the scene transitions when the player walks up to the telescope, and with that oscillating red green pattern (and a metaphorical sentence) it fades into the puzzle scene.
Then, my personal feedbacks, again some you guys might already know: I find the camera to be moving along with the player a bit annoying when solving the puzzle, because for this kind of puzzle I always would want to see all the dots to plan out my routes. With the perspective shift, sometimes it's a bit hard to tell the length difference between paths when they are on different height. (As for the part outside of puzzle, I have zero complains, it was way too good)
Anyway, really really amazing work!! I whole heartedly enjoyed this 10 min experience. I would really just sit on the chair with the hand underwater surrounded by hexagon wall to contemplate. That seems like a life I wanted.
