As far as more complex stuff goes, I think later games will be more exciting because with each game you slowly work out of the "box" framework of going from screen to screen. Think of Sub7 where the South Gardens and Winter Palace are much more free-flowing and have more interesting shapes, whereas Sub1, every room is pretty much just a box with objects.
So yeah, those are the "more interesting" games, in a sense.
I'm not sure I'm going to add the blue Karma Portals, though...they only show up when a person is near them and I'm pretty sure my rooms aren't really set up on a good scale for the person to go through them anyway
. I'll probably do the big white karma portal at the end of Sub9 and maybe the one at the end of Sub8.
Which leads me to layers...
The Layers in Sub8 will work okay, but in Sub9...geez. I didn't look that far yet. Maybe I'll do one horizontal strip of the Pyramid and other areas at a time... and then for rooms where multiple layers come into play, I'll just copy those rooms and, line them up perpendicularly with one of the Layer representations in the middle.
Here's a somewhat logical graphic interpretation of that:
For instance, a top down view of the Third Row of the Pyramid from the top would look something like:
---------(3a)
---------(3b)
---------(3c)
(1) (2) (3d) (4) (5) (6) (7) (8)
---------(3e)
---------(3f)
---------(3g)
1. Left Shaft
2. Corner Room w/ Bowl
3. a. Layer 1- Iron Pedestal
--b. Layer 2- Gray Stump
--c. Layer 3- Shattered Pedestal
--d. Layer 4- Weathered Yellow Block
--e. Layer 5- Iron Pole
--f. Layer 6- Brick/Stone Mound
--g. Layer 7- New Pedestal
4. Room w/ Ladder Rung
5. Room w/ Ladder + Brass Bowl
6. Room w/ Ladder Top
7. Scarab Room
8. Right Shaft
Hopefully that explanation made sense!
