I think it would be a fun addition to, especially in random dungeons, have "blacked out areas that in reality is is a room section .

Pressing e.g. a button in a computer console could open a secret door revealing a room or corridor not know to exist before.

This can be used in quests, extra bonuses or integrated in intelligent ways in the storyline.

The Crusader games (this doesn't make me younger...) used that with great results. I am in favor of this, but it's a nice-to-have feature nothing more.

Hm... The game have lamps, that make the terrain brighter. Maybe is possible
mess a bit with the code to create a invisible lamp that darkens the terrain
instead?

Like the "Impassable Tile", is invisible. Us can del with del_obstacle(). I just
wonder how could us adapt this code piece...

This appear a good idea, and I am also in favor of this. It's intersting,
however, as ahuillet said, it is not too much important right now.

We can actually set the global light of a level to be quite dark.
However, giving an obstacle negative light strength does not seem to work.

As I took a couple of hours to check BT I 
will comment this have some not-
intelligent implementation in Act 2 
(secret boss área) and on Level 24 
"Falling Ground" (which seems to use too 
many code lines imao). Also during Act 1 
end, when we add the stratopod...

In other words, you delete a wall and 
create a corridor to An already mapped 
room. Definitely doable, just complex, too 
long, and no one really willing to do 
it...
