I played this a long time ago and I couldn't solve it. I now started it with a fresh mind and almost managed it but one of the last steps (1:58 in the video) didn't come to mind. It's a great puzzle so I didn't watch the video back then because I wanted to solve it on my own but after keeping this map in my queue for such a long time I wanted to finally get it over with.
Still, I appreciate the work you've put into it. And after that little hint from the video I did solve the rest of it. Thumbs up!

I spent like 2 hours on this map.. ended up checking the solution, I hate myself now for doing it becouse of how far I had become, I already had both cubes on the bridge and it just didn't occur to me to make a portal for the laser shooting up from under the bridge guess I was heavily tilted, been losing my mind on this one, this is the first time I've ever had to watch a walktrough to finish a map. It was very challenging and very well made map. upvoted.

Very nice map was pretty challenging, you get a follower!

Yeah, that's understandable. Hope they would have fixed that by now though. Also, I had to place one of the portals slightly higher than the other to fit it on one panel, if I recall correctly. It was a bit finicky, but I could always get it to work after a while.

Yes - I think it's a bit too late to update this puzzle, because I always seem to get a new URL, and it already has some favorites and comments :( So the best I can do is update the description.

I *thought* that it was not possible to place two portals on a 128-wide surface (I swear it didn't work when I tried!)

[Part 1, read first] So after completing the puzzle, I watched the video and realized I used an unintended solution. I have a few screenshots of my solution below.

The first screenshot shows how I was able to place two portals on one panel, and then position the cube to redirect the laser through it. This caused the excursion funnel to change polarity, which allowed me to get both cubes up onto the hard light bridges.
(I can provide more screenshots if needed, I didn't expect this part to be an exploit, although it's obvious in retrospect.)
This let me get both cubes onto the opposite side of the big emancipation grill relatively easily. I then did the same two-portals-one-panel exploit, which let me redirect the laser around the corner and open the door, as shown in the last two screenshots.

[Part 2, read last] After finding the second exploit, I realized that this probably wasn't the intended solution. Watching the video made me realize where I tripped up, as I had gotten almost to the end, but I didn't realize the laser could be shot up from the ground. Hope this helps, and if you want a suggestion to fix this exploit, you could add one light strip to one side of each panel, which will prevent two portals from being placed on it at once.

Third one!

Noooo i always forget about cube throwing

Another one

I found unintended way

yay!! got it without looking at the hint. wow great map! favorited!!

Yes ;)

ok i havent looked at your hint yet. is this the intended solution. if not i will have to look at that hint i set it up so one cube is on the bridge in front of the portal surface thats a bit higher than the other one. then i took the other cube over to the bridge not connected to the laser. i have a portal at the funnel on the wall and a portal under the bridge. i dropped the cube down thru the portal and it knocked the other cube off the bridge and itself too. then all i had to do was go to the portal surface near the orange funnel and go into the exit area. cross my fingers but this seems right

Hint - You're on the right track with the "dropping a cube through a portal" thing.

Bigger hint - Play my map "Friction" - :)

well i have an idea. i cant pull it off but i bet someone could. both cubes up on the bridges. open wall to exit. put a portal on the wall . grab one of the cubes. put a portal beneathe you on the floor. fall thru the portal and if you are really great land on the bridge with the cube.

oh boy, can you give me a hint. i can get one cube and the beam and myself in the exit area. its that second cube thats giving me trouble. i thought maybe i could place it on the bridge angel a beam at it from underneathe and then hopefully it would fall off onto the portal surface. obviously that doesnt work. i so want to solve this. any tiny hint without giving it away.

oh man. i cant figure this out

jandlml - Nope :( I always forget you can do that

Near - Yeah, i think it's a bit of a mean trick, tbh. I thought about including a button to turn off the light bridge for 1 second, but I think that is too much of a give away.

ok i hope i did this right. i couldnt find any other way. and i didnt want to look at the walkthrough yet. but you said it was a trick so was it a double portal on the lower portal surface in the exit room. cross my fingers?

Your version much harder than mine. I couldn't see this sneaky move, assuming that you can't throw cube down because of light bridge. Anyway good job there!

Great puzzle. I played @Near's version a few days ago, but this version had me stumped and looked at 'that bit' of the walkthrough . Not sure if I would have got it in time, but wish I had given it a bit longer before cheating :(

I see you've already fixed it. Nevermind. :))

I didn't want you to lose that bet you mentioned earlier. :P
