Sorry for the mappers reading this. Please note my intent is to provide helpful feedback. I am a very blunt and technical person so please don't read any sort of ill-willed tone in this.
The central atrium is very confusing.
I like being able to look down. However, From the top floor it looks very messy in terms of z-levels. The central park area is nice, but the railing are not needed. This is a specific complaint about a broader dislike of the map- the needless stairs and "fake" z-level changes seemingly everywhere. During one of the test rounds I asked a few in LOOC if they could tell the depth/perspective, mainly from standing around the coffee area. It just looks confusing with all the rafters and railings. Some simplicity in this area would be better to convey how deep things go. No faking z-level here would be preferred.
Continuation from this, the catwalks/partitioned and glassed-off walkways on the side of the levels here. It's odd. What are their purpose? Functionally, it is on the same level as the flooring surrounding it, but there is a tile missing with railing all over. Why not just make the flooring go all the way to the walls?
I'm lazy, and the map isn't up right now, but picture something like this:
And with it surrounded by railing, I just don't get it. It uglifies things to me. Again, the whole center atrium z-level perspectives need some work.
The legitimate z-change in one of the restrooms is odd. You enter the restroom via a door, and in the area before the stalls there is a staircase. Double-decker shitting? No. It leads to directly into a hallway above 1 z-level with no entryway/door.
The best way to explain my pain of this restroom is through memes.
