: I restrict labelling areas '5-D Space' unless they share not only the same xy
: location but also an overlapping z. Otherwise The Hard Stuff would just be
: one massive 5-D level... but, if you play through it and then compare with
: 5-D Space (the netmap), you can clearly tell which one is and which one
: isn't.
Come to think of it, I think Hard Stuff was also one of the few levels I didn't find 5D in. Probably because each floor was restricted to its own range of Z coordinates. But I don't have a Mac here to run Map Viewer and verify that.
