Idea that nobody so far had implemented - Read before giving conclusions!

[Hardarm]

This is an idea i've been working on, but mine depends on repetitive action of investigation without any items and without any "hidden" areas. My project is currently postponed due to entity animation issues. I already have the system planned out and the map laid out (though, not in the shape of a maze), but unless i overcome this animation issue, it won't have the same effect.

Nice, i'm looking forward for it.
But you see, the "area sequence" idea is one of the easiest i've came up in mind, and it's one of the easiest to execute, kind of.
