This is certainly a high quality visual novel. The art is beautiful, voice acting on point, and I appreciate it goes out of the box with exploring anxiety. However the story missed the mark for me.
Lysandra is a bit...confusing. Aside from anxiety she seems to have extreme paranoia regarding her brother's motives (being kind to her and others). 29 and refusing to eat something just because he brought it to her, seriously seeming to want to kill him during that training exercise; that just seems to be way more than anxiety to me. She needs counseling, not a relationship right now.
While Ramon's developing feelings for Lysandra came off as more authentic, Lysandra's feelings for him felt more like those of dependency, not budding love. They COULD become mutually genuine, but the vibe I got was: you have a severely mentally unwell woman (who has suffered family trauma) latching onto the first person who makes her feel seen, instead of getting the professional help she needs.
And then there's how quickly the perceived conflict with Lysandra and her brother was resolved. This is someone she has allegedly HATED for years (since at least she was 15) and that all just goes away after some spying and one conversation with him? Again, with how severe Lysandra's trauma/resulting mental health issues were made out to to be to the player, it just seems too neat.
I'm sorry to be so critical; It really is a beautiful game, with a lot of potential. I think the writing and voicing of Ramon was done very well, and the world building was just enough to get into the story (I especially like how it's set in the same world as "Fling with a Tiefling" -which I thought was really sweet and spicy!).
However, while I appreciate the attempt to explore an MC with mental health issues, it just needs some polishing. I think it would have been a better story if the focus was JUST on Lysandra finding a healthy way to cope with her trauma, instead of also adding a romantic sub plot.
This one wasn't for me but I do plan on exploring your other works as I did enjoy "Fling with a Tiefling".
For those interested in playing "Your Blade, My Heart" I advise you to stick with the MC persona as this is a VERY particular -basically linear- story, and self inserting might be awkward.
