Hello, I just finished reading through this VN. For the benefit of anyone reading this: No story spoilers in this comment, but I do talk about the author's note some and a few themes which could be considered light spoilers.
I was pleasantly surprised to see Otoboku listed as one of the two main inspirations in the author's note, since it's where my mind usually wanders to when I think about this type of setup (I also read the VN and could see the similarities in vibes). I'm unfamiliar with the Claudine series, but it was interesting to read about what you pulled from it as well.
I really enjoyed Embraced by Autumn a lot. Having read through some of your earlier VNs semi-recently, it was interesting to see how your style has changed and improved (and also generally appreciating the sheer variety of stories you take on). You do a great job setting the vibes, and this has been my first time in a long while just diving into a VN without knowing much about what to expect. I really enjoyed Marcel as a protagonist and the themes of identity (not even just limited to Marcel, now that I think about it).
The author's note has a mention of a hypothetical Noémie route. When first reading through the common route/prologue, I had no idea who the four love interests mentioned in the description were and wondered if Noémie was one or not (in hindsight I think paying more attention to the screenshots on this page would have clued me in, whoops). I did enjoy her role in the story, but if you ever do decide to return to the world of Embraced by Autumn, I would love to see what her route would be like. Of course, if you have any other ideas for the setting, I'd be interested in those too. I understand you have other projects so maybe you won't be able to return to it, which is perfectly understandable. I wish you the best of luck no matter what.
Thank you for this VN, and thank you to everyone who made it possible. I have put the shortcut to it next to Otoboku's on my desktop, because it only felt fitting to me to see them side by side.
