I'm not Morenatsu's biggest fan, it's just a silly visual novel that brings up some summer-ish feelings, it just makes me feel comfy, even if I think the original's writing was kind of mediocre. I'm glad someone is rebooting it, there were some things that needed to be finished or rewritten, mainly because the original Morenatsu team used to have different writers working on different routes while not communicating with each other, and that resulted in some inconsistent characterization of Hiroyuki and some other characters.
Now, you're giving the characters some dimensions to them, I can feel them being more complex, and that feels better than the original.
If I had to complain about something, it would be about the characters' color palettes, they're very dull and gray, they don't give me that feel of summer, warm colors, idk. I recommend applying more saturated colors, or using different palettes for the many weathers and times of the day (rainy palette, sunset palette, etc).
