I want try to generate some large map out of prefabbed rooms, and think it's too big for single level.
How about transition-hub functional like q2?
I think it's not implemented now(And I'l be happy if i just miss it), but as game with already good save functional, it's views not so hard for me.
Me be with engine evolution for next project? (I am not request this now, just curious about... Because a really large maps with backtracking is my passion. Zortch already good at this, but i want moar and bigger)
