Since there isn't a downloadable version on the itch.io page as of now, I'm assuming the browser version is the correct one. It's a gorgeous looking game, and the sound design is really wonderful, but I'm not really able to get past a couple years. For me at least, it's difficult to tell when a piece of geometry is going to be steep enough to cause a reset, and some peaks and valleys feel almost impassable without really precise inputs. It's likely just a me issue on some of these things, but altogether it's a really atmospheric piece of art
Edit: After some repeat tries, I realized you could double jump, which helps a little bit as well
