This is such a cool experience! Short, but really well executed. As others have mentioned, the game looks gorgeous. The low-poly style and the dithering really give this a cool, ethereal aesthetic. I also love the juice of the little flashes as the coffins/dominos come into existence before toppling over (and the sound design for that was great as well). The falling segments also kind of caught me off guard, and I found myself feeling bad for the coffin/domino thing (before that second area). I'm having trouble finding the words, but the whole vibe definitely made me feel something. Kind of a lonely/sad/wistful tone. Even though I'm not sure how to describe it, it was very cool.
I'm not sure whether I agree with the previous comment about the controls. I kind of liked that they were a little bit out of the ordinary and required some thought to use; my only remark on that front is that I wished I had a little bit finer-grained control over the angle; I found myself trying to click-and-drag but being unable to, so I needed to click away to a wildly different angle and then back to find the one I wanted.
The puzzles here were not particularly tricky, but I did need to backtrack a couple of times to find the right size. Once you've figured out the mechanics, I like that it didn't require a lot of stop-and-think with each new puzzle, and I could just focus on moving through the environment and enjoying the atmosphere.
I'm so glad I played through this one; really beautiful stuff. Fantastic job!
