Really liked this! Your VNs are always amazing at giving off this very strong and unique sense of place and time that I don't see very often. The presentation is gorgeous, and there's a lot of attention to detail. Love the slow dripfeeding of how messed up Ys is.
I'm not sure how you feel about UI feedback, but would it be possible to increase the contrast between the 'talking' and 'non-talking' sprites? At times, it can be tricky to determine who's talking.
