Description
One single laser is used throughout the puzzle. There are reflector cubes used along the way to redirect the laser as you progess. There's a bit of back and forth, but really there's no excess walking. It's just a matter of jumping back down and returning through portals. It gets a bit tricky as you progress, so I would rate this between medium and hard.

Alternate solution for ending: https://youtu.be/sK6qfHkJuCQ

I suppose. I'll watch both videos and compare. This is because it's been 3 years since I uploaded this map and some of them I've forgotten how they work.

Ha ha, I see by your walkthrough video that it wasn't intentional. I guess I figured out a solution with one less cube at the end. You wanna see how?

Didn't seem to need the laser catchers or high-up cube in that last room at all. Was that intentional?

There is a place where the player can get trapped. Using portals to guide the laser to hit the laser catcher in the mini fling room. I was able to achieve the angle. Then on accident i deployed a portal supporting the laser on the angled panel. I had both potals with no laser to get out. To fix it may I suggest to right justify the laser catcher to make it impossible to hit it on an angle using portals. The player would give up and may use the intended solution path :)

More than a year since the last rating! Well, that was a convoluted series of moves at the end. And I mean that in a good way. Set up this so you can do that, which enables you to do the other thing, which lets you fly by an opening at a certain angle so you can fire a portal, so you can ... What a workout!

Nope, I accidentally shot my second portal outside of the room where the laser was hitting the cocked panel. Without that portal, there was no way to go back or forward. This was my first run through, so it's easy to make mistakes.

I can't imagine how you would get stuck, because in order to get into that room with the fixed angled panel that keeps the cube cocked on an angle, that means you've already acquired 2 cubes to bend the laser actually into the room. In the walk-thru video, you'll see the second cube stays there bending the laser into that room, and then when you get the 3rd, you use it to open the door then back-track a bit. Or perhaps did you bring the second cube into that room?

Okay, I guess I broke your map. I am stuck without the ability to go back or go forward.

Details: I got two rooms past the room with the button that disables a laser grid in the next room, and triggers an angled plate in that room. Once I got to the room with the permanently angled plate designed for a light box to redirect a beam 30 degrees upward to a wall laser trigger, I couldn't backtrack to shoot a portal in the first room because the door between that room and the one after was closed. Making it impossible for me to go back, or go forward. I liked every part of the map up until then. Fix that, and I'll replay it. For now, neither a thumbs up or a thumbs down.

Great chamber - kept me thinking the whole time!
