Oh, I think I haven't come back to talk about Chain's route. (Gotta admit, I'm still partial to Roya though, haha.) But I enjoyed learning more about Chain and empathizing with him, learning about the hunters and this whole other aspect of your fictional world. I was proud of myself because I managed to explore most by myself, there was one bad ending and its achievement I needed a guide for. Odaz and Zuri were so lovely and they deserved better ;; Also liked the insight we got into Rasumi's backstory, I find such "meta-narratives" interesting!
Btw, I think I might have seen something about it somewhere... don't know if you talked about such plans, or other players suggested, but do you plan on updating the original game with the new art? Would make replays even more enjoyable. IMO Junoru and Ikuya had the biggest glow-ups!
