Some of the walls like that are just non-solid brushes with tele triggers inside. But it is a bit annoying that stickies can't go through the frame of the trigger. And there is a level somewhere in the early part of the map where you can't properly prefire because of that.
Why not make it just 1 solid wall without player clip? I was expecting to airpogo there and you can jump above 2 first platforms but not the last one.
Same for this one, why not just extend the wall up to the celling?
Anyway, I'm not really sure about the spacing, I'm not the best demo but it looks decent, not too dark like a lot of other maps.
