This is really a simple puzzle. It loops in on itself with obstacles; unless you and your partner can work together, you're both going to be doing alot of exactly what the title says.

Lighting and texturing were top-notch, definitely nailed the decayed Aperture theme. I also liked the use of "laser music" which gets used surprisingly sparingly in custom maps.

Not a fan of surprise turret ambushes. Also, once the turrets are destroyed, you could probably leave the starting glass wall retracted permenantly.

Generally I dislike coop maps that require one player to basically stand around doing nothing. Maybe we played this map wrong, but the person who stands in the glass room with the one reflectocube dropper does just this - they place the cube in it's position and then wait for the other person to complete the rest of the relay puzzle.

The "upper area" could really use some sort of better visual cue that it's there. Me and my partner totally did not even see it for easily the first 10 minutes. The puzzle itself also required very little "thinking with portals". I think the idea is really solid, and maybe instead of giving the player an extra reflectocube or two, you could have a few surfaces in the puzzle area be portalable.

A coop map so good, that it can be soloed. Now that I think about it, the map not working in coop might have been a red herring: we had to rename it to mpcooplaserglasses.

TBH I didn't find much atmosphere here: it looked like Clean with a few decay elements. That flat room with low ceiling gave us flashbacks of some very old fps, regarding style that is. Puzzle's not difficult and presents this interesting treasure hunt before the proper laser puzzle begins, very forgiving and adequate for beginners. Moderately fun, at least for the one player who's playing.

I'm playing custom maps and record my first time of playing them. So the run is not perfect and may not use only intended ways, but maybe it can let you see how other people may understand the map or you could just enjoy someone playing this map for entertainment.
Anyways, here is the recording:
