This is lovely. Geography and career have kept me from cons, but I'm ageing, I have too many degrees, and I have a cel collection, so I certainly felt aspects of this. Plus it has yellow text, over images in 4:3, the most virtuous aspect ratio!
Also the detailed written texture in VNs doesn't always get enough notice, so I want to say that I liked how crisp and tuned much of the dialogue (spoken and internal) felt. Nice variation in syntactic complexity, and a sense of two different register-sets for the two characters.
