good map
had a problem timing the exit.
many, many attempts.
kept getting caught on the top of the exit ledge,
then would get caught on the top ledge of observation room below.
probably my lack of skill.
at the begining, I thought I was supposed to do what I had to at the end.
your good set up in between inhanced this map a lot.
I got traped just past orange tractor beam.
I only had 1 cube.
my bad (had to restart level, as saved on getting there.)
apart from frustrated trying to exit, I enjoyed this map.
did it in the end, stopped using eyes & timed it.
