Wow, this is an amazing sensory experience. In terms of "non human perspective," I found myself stumped in realizing the legitimate perspective of the thing I whose perspective I was representing through visual signals instead of mechanical inputs. This recognizes the visual signals I think perfectly. You have a very strong taste and even more important, you have the ability to realize the taste in reality.
Critique: This seems more like an audio-visual experience that would be a part of a Bjork or Arca music video or something, so it seems like the player input is almost secondary to the experience. There is the feeling of confusion and trapped ness that I am experiencing from the suffocating darkness of the world, and I can tell this is purposeful and does interact with player input, but in reality I struggle a bit to understand what I am doing and if it makes any impact on the "game state." I guess, you need to reflect and think, "is there a game state in this work?" "Do I want ludology to impact user experience?"
