Hello,
First of all, I'm sorry to respond to an old topic, but I found it during a search.
Kiya's screenshot is an exelent example of something I've noticed.
As you can see, most of the map is still black, but if I scan these hidden parts pressing the shift key the mouse arrow indicates that there are torches, barrels and so forth, hence I assume that there must be further rooms.
Either Kiya hasn't been there yet (It seems though that she has played the game thoruoghly and probably made the screen after she completed the game or at least the abbey)
Or there is no way to get there.
Does anybody know something about that?
