A very polished and fascinating look at three characters through a unique lens. I found myself interested in the background of the story, as it seemed to be rooted in some other work, but was still able to more or less follow along with everything which was in front of me.
The influences are very obvious, which I don't think is a bad thing in this scenario, honestly. It lends a different angle of the Gensokyan lifestyle which I don't terribly think is explored very much in general. In that aspect, the story earns my respect; the characters are all down-to-earth and speak like long-time friends (and associates, when appropriate.) The world is built impeccably through dialogue, and reveals a very intricate sense of humanity, which I appreciate. It isn't often that the relations of humans and youkais are so frankly expressed and I was pleased to see it tackled here to an extent.
The characters are also peppered in personality. (Mokou being a smoker just feels right somehow, and Youmu setting her swords up next to her as if it were another person was also a nice touch.) Their motivations and intricacies are evident in how they talk and express themselves. Good touches, all around.
The use of LGBTQ themes is some of the best I've seen portrayed so far; it is willing to explore some very personal and invasive topics and does so with both respect and delicacy. You could really feel the plight of the characters as they danced around the topic and then confronted it in a reasonable manner. That's hard to pull off without coming off as a checkmark or otherwise feeling plastic, but you did here.
This is a great work and it's even more impressive when considering the polish it had while also being completed in the timeframe. Please continue to make games in this universe with us!
