What a very unique experience! I haven't played many VNs like this, where the choices are abstracted into pictures, but it's very memorable and interesting! The aesthetics are great as well, and really help the game stand out. Aeon is a really interesting character, and I enjoyed learning more about them, seeing how my different responses to their questions changed their attitude.
The writing is really interesting; I love the use of repetition for the sleep/waking cycle. You can really feel that desperation to return to the dream, where Aeon waits, and the panic of being locked into a unresponsive body. It's really effective stuff. I'm glad I was able to reach a good ending!
