I find it interesting that the series is meant to be played out of order. But I assumed 0 meant.... the origin. But it's hard to tell what comes first. Especially because the story already feels so full. Having read Glow of Honeydew as well, I can see how these kinds of girls. Girl who longs for touch because she is so lonely, and girl who wants to please so desperately, how these sorts of girls seem to come naturally to you, in terms of writing. And you write them so well.
I would not be surprised if I saw more girls like this, more pairings like this, in your other work. I think you have a way of writing stories that feels almost dreamlike. There is a certain surreal haze to them. It creates a quality I enjoy. There are games from so many people I have met and interacted with in my mind of games I want to play, and each and every time I am surprised and filled with joy to see what people have made.
I am happy that I am starting this journey into squid girl world. I want to see what else it holds.
