Me: This chamber brought our love for portal community maps back, after years of looking for gems among brainless and repetitive chambers. It showed me how our minds complete each other, with me thinking what should be done, and my friend - *how* to do it. Your contribution to our relationship is immeasurable.

Friend: after unexpectedly failing the first attempt to solve this chamber, I was forced to once again admit that there are things complicated enough, that the only way to understand them is to analyze and decompose it into a big bloody State Machine chart, plotted on a piece of paper, like good old times. Before, only a small selection of puzzling things were subjected to such procedure.

Very good puzzle, I thought the portal management involved with having access to both funnel and light bridge while getting to the three dots section was really wild! Thanks for making it, we really enjoyed :D

What an incredible map !

The amount of thinking needed was insane and the logic was awesome Favorited !

Here's our blind playthrough of this gem : https://www.youtube.com/watch?v=R-QGdGOMH44

insane. took us 211 minutes and 100% brain power. 11/10 experience, thank you fumbly bumbly

insane puzzle. took us 211 minutes and 100% of our brain cells. a wonderful experience

Me and my friend gave this one a go. It took us 3 sessions to beat it. The complexity of this map is insane and I'm still trying to wrap my head around how someone can come up with this type of puzzles. Amazing work.

Very interesting puzzle with elegant portal management,big thumbs up!

...and I have finished all your maps. Awesome puzzle! I agree with the hard difficulty rating, though funnily enough, this may have taken me less time than Rivulet :p Anyway, absolutely beautiful portal management. I agree with quaternary. Very satisfying to finally solve. Definite favorite. I'd love to see more challenging maps like these at some point :]

Splitscreened this one. Wow. Incredible test.

I like how there's two ways to reach dot 3 - the obvious way that instantly gets you stuck, and the far, far more subtle way that lets you pass.

Would have been just as excellent if the exit was reachable from the ground, but unlike most cases where there's an extra step thrown onto the end of the puzzle, I like the exit being raised up. It's like a little encore to prove you really know your way around the map and how to use portals. (I did use the grated surface in the exit room.)

You've caused us a lot of sleepless nights.
Finally we can get some sleep again.

Wow. Seriously incredible, by far my favorite coop map I've ever played. For a map with such a small number of elements and connections, it is seriously difficult. It took us over 2 and half hours to finally solve this one. But through the whole thing, we could always tell when progress was being made or when an idea was useless; an aspect that I really appreciate in a hard puzzle. A multitude of connections or a crazy layout can destroy the sense of progression the player feels during the solving process, simultaneously making it a more frustrating and less rewarding experience. Thank you for creating this...really opens up a whole new level of coop logic and portal management (at least for me). Love it :)

Insane shit! Good job!

Yet another truly excellent puzzle. Took me a fair amount of thought to get the middle sequence precisely right, but it was very beautiful and very satisfying to solve. I think we've played all your co-op maps now (correct me if I'm wrong), and I must say, I had never imagined that such a world of intricate conundrums existed beyond the regular spectrum of single player maps - thank you for showing me this. This one gets a definite favourite once more :]

You cured my depression twice!

(2/2) But this chamber, this specific chamber, is propably the most difficult chamber I have played yet and I had this "I have no idea what to do, I tried everything I could think of multiple times"-phase for a prolonged time and even after a night of sleep and after writing down a list of around 80 steps to solve it, I still could not fully explain to anybody else how it could be done. Well done! Even a +3 would be a lousy "average" vote for this level of your work.

I also love that you do this just with vanilla elements and skins. A few of the other "good" creators try to hide their puzzle behind different skins or elements, that you first have to learn, what is a bit strange if it is a mixed list with totally different creators in between. So very well done, you clearly have a talent for this!

(1/2) I played a lot of Community Chambers over the last years and most of them are boring as hell (like: I press a button for your door to open, then you can press a button for my door to open.. or like: endless continuation of plate-flying.. or ...) and then there are a few creators with a skill for very good chambers, of which you also have a lot. The chambers that make this subtle switch of realisations like "oh, that looks easy", "hmm, no, this doesn't work", "but I have another idea, let's do this and this and this and then it is solved", "oh sh** that was intentionally prevented, what now?" and after 5-10 rounds of thinking you have a solution, maybe you have to redo what you already did a few times, but then it is solved. That is what makes a good chamber an I am always sad, that there is only a +1 to vote for those chambers, like a skale from -3 to +3 would be much better.

Thank you, @Nobody No-One! Yes, I would still really like to remake it. I think it especially relies too much on fizzlers and a general convoluted layout, which I would really like to change. However, it will be a very large project so it won't be finished for a while and it will likely take some time for me to even begin working on it. It'll be a very satisfying challenge to twist around the design of such a complex puzzle to improve it. I'm so glad you enjoyed!

Excellent map. I solved it like ShinDog's first video (no grated surface at the end). It took a lot of thinking to solve due to all the portal management, players switching places, etc. Many times, I thought I had progressed only to find out that one or more of the players had lost portals that they needed to have in order to continue, and I had to go back and reconsider what to do. It was very satisfying when I finally got both players to the exit. Thumbs up and definitely added to favorites.

Are you still considering remaking it? I agree with some of the comments below that the design is a bit grating-heavy and not very open.

Nice map, quite hard puzzle , took some time to solve it. Well done!

I'm not sure, but maybe this information can be useful for you. In my humble opinion, "Stabilize" looks great and it does not need any update. But you, of course, know better.

Yep, that's intended. I don't have the map file anymore, so I cannot update this puzzle. If I were able to, I'd actually remove that grated surface and enforce your solution instead. I might end up remaking it, though, and I will change that if I do. It would be nice to give it a visual update, and I'd like to experiment with making the entire chamber more open and visible, as I think the layout could be better for this one.

I think I figured out how to use the grated wall surface at the exit. Is that intended ?

Thank you so much! I think you solved the end slightly differently to how I'd originally planned, since you didn't use the grated wall surface at the exit, but that hardly matters. Everything else you did to get to the exit area is intended. Thanks for playing, and thank you for the video!

Amazing puzzle! It took us a lot of time, but we finally solved this brainteaser.
I recorded the walkthrough. Here is a video .

Definitely, you are the one of the best puzzle creators in this game. Thank you! :)

I really really liked the position management you put on the player(s).
Only complaint: the sightlines for the map are really grid-locked so it's hard to see parts of the map from other parts. Not very "open" in my opinion so we had to noclip a few times to see what was going on around the exit before we made a plan.

Thank you! Glad you enjoyed.

REALLY WELL MADE MAP, wish I could say the same about my partner.

You won't believe it, everytime I write comments like this, the solution pops up the next day ^^
So it's not urgent anymore, but there will be others who will be grateful :-)
Anyway, great chamber again!

I will make a solution video when I can.

This chamber urgently needs a walkthough video pleeease. We solved the beginning and we can see the final steps, we just need a centerpiece now :-(
Regarding the final step(s), I'm pretty sure we need to find a way to replace the funnel by extending the bridge in order to make one player cross the goo. We see no way to maintain the bridge once this player crosses the jumping / momentum part.
Give us a hint at least.

@Désa Thank you very much! :)

We lost our brains but we did it
Awesome map well done sir
