Find the rooms nobody can enter and check each has a way to be found

A hand-drawn dungeon often hides a room by accident, and a secret room is only fun if one thin wall gives it away. Here is a check that lists every sealed room and the wall pieces where a secret door could go, and warns where the wall is too thick for that.

Why this works

A secret is only fun if it can be found. Separating what the player can walk to from what they cannot shows every room that is hidden by accident, and a single thin wall is the one kind of clue that makes a hidden room discoverable.

When not to use it

Skip it for a dungeon where rooms are reached by digging, flying or swimming, or for a game with no secrets. Walking is then not the only way in, so the check calls good rooms sealed; mark those paths as floor or ignore the result.
