Worlds ceiling floor implementation idea

This is most likely not going to be implemented

In normal roguelike you have all rooms with ceiling and floor, this idea is to have the ceiling/floor from the room above or below. This needs to be considered...

Side profile examples, @ is player # is tile.

Layers are worlds Z coordinates values. In short, when a actor walks on ground, it walks on ground on the room below. This prevents from having one "floor" layer between all

n = player's current Z level
Side Projection
(n)  :  @
(n-1): ######

Top Projection
(n)  : .@....

Example of a down/uphill

n = player's current Z level
x = player's current X position
Side Projection
Depth(n)    @ ^###
Depth(n-1) ###^   

Top Projection
.@.¤¤¤

Player moving down the hill...
position(x)    ..@^¤¤¤
position(x+1)  ...@¤¤¤
position(x+2)  ___^@..
position(x+3)  ___^.@.

¤ (or some characther we choose), is going to represent downhill.

Maybe _ should signify a floor (or something) on a deeper z level while that way it's easier on the eyes. Also included ^ character as a notation that theres a transition from Z +/-
