I've tried this route before, except I got caught by the floor master in the small key room because it seems faster. I really don't know if this route is faster or not. I think this should be timed properly but it would be cool to get rid of the dark clip because that's kind of annoying.
Thats a good idea. I've been trying that out. Haven't timed it properly but it should be come out even or faster. However the floormasters don't always seem to spawn, not sure what causes this.
