The "school" is empty because creators were lazy and couldn't be bothered to fill it up with background and support characters.
The character routes rely heavily on recycled tropes and derivative plot points that lack originality.
The worst one is Amane backstory. It's beyond retarded: one giant contrived drama with characters making irrational, nonsensical choices for the sake of tragedy. It's cheap, fake and boring.
I would say beware of that trash eating your braincells, but the target audience of this "eroge" doesn't have any braincells to begin with.
