We need another word for how genius this puzzle is.

cant beat it

had a tough time on the last couple of steps the solution taking a break for a fresh perspective I gotta say 10 out of 10 level design.

Beautiful

This chamber got a bug. You can get null portal after getting up a stairs first time, so you can solve the chamber by accident. I went the intended way.

My satisfaction cannot overwhelm my frustration

Very clever. Probably the hardest chamber I ever played

I didn't have the brain cells to solve this, superb puzzle!

Just about made me lose my mind. 10/10!

nice map, but my brain hurts

i hate my life, thanks

very good map i really enjoyed it :)

i think i accidentally beat it before i was suppose to. i did it with only solving the first laser puzzle

Wow, timing tests are not my cup of tea, but I can appreciate the genius of this idea!

I finally beat it... That was hard but the challenge really well made !

EYYYYY!!!! also who knew downloading way to many workshop maps would make my portal 2 crash- (don't answer that. please..)

I SAW THE VIDEO FOR THIS!!!!

Nice! Really satisfying at the end

That's some really good puzzle design, I'm glad that Mike Daas made a video about these and that I was bored enough to watch it because I feel like I just found a whole vault of unused (by me ofc) test chambers.

I'm not sure about this chamber. While the solution is interesting, and it does have some innovative ideas, I'm pretty sure that if you make a mistake at any point you'll have to walk all the way back to the beginning, and start the process over.

This puzzle just destroyed me at the end. Brilliant job :)

brilliant!

loved it, absolutely insane and lengthy process to do such a simple action, made me feel like a complete idiot once i realized what the solution to one part of the test was only to get immediately stumped by the next section, 10/10

Yes, I've added the panels after the puzzle was finished, so that you don't have to use the laser every time you need a new cube after you did it the first time. It's a funny oversight and only possible when you restart the map, so I left it in. It should be obvious this isn't the intended solution and will leave the dedicated puzzle-solver unsatisfied.

great map but it is pretty easy to chease
i activated the laser and used it to power the stairs and climbed them before the timer ran out, and used the new portal sufraces that come out of the wall to fizzle one of my portals, and then I placed a null portal under the cube, stood on the button and placed the other portal above the funnel

ok... I also removed the portal whit the Flip Panel, but now I feel stupid xd
outstanding test!

I did it, but I think I cheated cuz I did a Flipshot at the end.. gonna watch the tutorial

I feel big-brained now, I did it without the tutorial, too!

this is too good

Absolutely f****ing genius.

I had a lot of fun with this one Favorited !

Coming from a lot of potential/kinetic puzzles I found this to be quite challenging. Great level design. Thank you.

Very fun puzzle. Quite easy but enjoyable.

Brilliant puzzle! My playthrough: https://youtu.be/xYcM5edtXwA

Smart puzzle! I liked how the whole chamber was working towards being able to create a null portal in the starting area.

Creative and really fun to solve :D

Defeated. Figured out the fizzler created null portals but had to watch the solution to understand the flip panel null portal used at the end

I really liked this.

Played on stream. Nice map

Good map! Came here from Redose

Excellent puzzle! It was the perfect difficulty level so that each step flowed fairly naturally into the next, but I still had to think carefully about several moves. Great use and reuse of elements, including the titular maneuver. The timing on the laser was a bit tight at times but it wasn't a huge problem. Thumbs up and added to favorites.

great last three puzzles, haven't played any others of yours yet, Did not need hints or video solutions but took me some time. you should have more followers!

Very nice map! https://www.youtube.com/watch?v=bcOMeCLeP74

Great puzzle! I didn't think of the ending move until I recalled the title.
Also sorry for cheating a little bit - it didn't occur to me until I edited it but I get the idea.
Playthrough video

This trick is the reason why there is only one white tile on the ground. I vaguely remember testing this, but I tried to shoot the portals from the button area instead and could never get them in the exact position from up there.
A tiny portal blocker would do the trick. Maybe I will update this if I can find the old Hammer file.

I enjoyed the map but it is quite easy to bypass the majority of it. I think you should shrink that portal surface some. https://youtu.be/WJSW4M-IaVM

If you're curious as to how I found this too, I found your workshop through wildgoosespeeder's Non-Exploitive White Gel Puzzles collection. From there I found Primer and decided to check out some of your other tests, if I remember correctly.

I found this map and others of yours through Mevious favourites collection I think.

Great puzzle. I was a bit put off by the timed laser at first, as I’m not a good mover(!), but even I could do it. The title helped me a lot, and after I worked out that I couldn’t get the cube in the funnel without it getting fizzled unless I had a..... I knew what I needed to look for, even though that ‘trick’ I’ve only seen used a very few times before.
