Well, it's no big deal to me, so I just brought it up half-jokingly. But basically the floating platforms break immersion a bit because they don't make sense from a logical stand point. SotN did a good job having a world in which areas feels naturally connected to each other, you really feel like you're in a distinct place, not just a series of separate video game levels. SotN also had floating platforms of course, but it had subtle explanations as to why they are there. You can see a crumbled stairway in the background in one such section for example. Later games kind off placed these platforms haphazardly around the levels, so it feels kind off cheap. It's a shame, since arguably this feeling of immersion was SotN's strongest point.
