	(3 should be enough for 5 dungeons)

Each room has some nearly-hidden "trap" switches that seal the way forward. If you accidentally trip one, you need to search for the "release" switch to open the way.

One locked door. Search for the hidden key.
Hide it in a completely different way in each dungeon.

See the goal. Search for the path that leads there.  (a maze)

The enterance to the goal is hidden. Search for secrets.
Finding this hidden door leads you to the dungeon's end.
	(clearly tell the player that this is the goal)
