This is a very cool experience. I think there's a part after you realize the first building sinks into the ground as you approach, that you go, "I wonder what the other buildings do", and it turns out they all do the same thing. It would be cool if they became unapproachable in different ways from each other (shrinking, your speed slows as you approach it, etc). Also, I was able to touch the arch before it went into the ground. Not sure if it's intentional. Vibes are great, especially the snow footsteps sounds.
