No time today, either, but: combined map screenshot! Behold Falling Water at 270 screens minus one! (I think. It's been a while since I did a proper count, area by area.)
Couple of notes:
The long horizontal line of screens, bottom right, is not part of the level (and not included in the screen count). It's just a series of concept sketches for areas still to be built.
The vertical line of screens in the middle *is* part of the level, but not part of the screen count, because it's just a bit of sky which I put there so as to have an axis around which to orient the level.
Oh, and the City, the part of the level you guys already know? That's in the upper right third of the map. Everything below and to the left of that is new.
