still great.
though I recently played your duplicate map:
GloomShine #59 (Return of the Cage)
obviously it was easier this time.
but I spread more speed gel in the 2nd chamber.
to reach the portable wall & to the other wall.
this helped a lot.
to get the speed gel to the portable area, in the 2nd chamber.
I had to gel coming out of 2 portals in the floor, in the 1st chamber.
untill they lost their hieght.
then fired a portal in the 2nd chamber.
for it to come out on the floor, just in front of the portal.

whoa that was tough; realized the reversible panel marked slash was not for getting over there, it was for getting back -- but like Petuski said, moon destroys the cube, so you gotta be prepared to get back to the first room!

Red tractor beam above exit was not necessary, except maybe for visual symmetry with red beam on the front side...

Stuck; I can tell I need to activate a slash somewhere so that panel can flip and I can blue beam across, but I can't find whatever controls it

Excellent wicked tricky use of all kinds of elements! Fantastic map! Getting that last pedistal button only to see the blue tractor beam lose it's portal! Great fun! Thanks!
