Personally I'd suggest at least for the interior, like for the house and city I suppose the beach too, have like an arrow you can click to several small pictures and the name of the zone that you can click.
Mainly to avoid people from for example clicking on the bathroom door when they want to go to the living room or the MC room.
To be clear that is not an issue of them being too close but of learning the layouts.
Though on another note this VN does have potential and if the updates are decently sized and frequent enough I'll most likely support it.
