Some issues I had with technical side of things. There’s no back button so if you accidentally skip a line, you can’t go back. And if there is a command to do that the VN never tells you.
I don’t like the solid pink when selecting a save file, especially when saving since it covers it up and make it hard to see if the save was successful. Maybe a transparent foreground would be better.
And finally the white chess pieces at the bottom of the screen can cover up some of the dialogue that reaches that far.
