As a CS student, this game is one of the very few games where I'm SERIOUSLY impressed by the UI. Like holy shit, it's so... Smooth. Especially for a visual novel. Just seeing the UI makes me giddy (I sound like a geek)
I told the UI artist and she was really happy with your comment. UI (as well as programming) is something that people tend to take for granted, so we are grateful you noticed!
Agreed, this must be a decently sized team of people if they're releasing a chapter per month with this level of versatility. Just the minigames alone require knowledge of so many different things in coding/programming!
