@SpielSatzFail thank you for your long feedback, I really appreciate it! :D This was my first map ever made, so it can probably explain why it's so tedious. When I was only watching portal 2 videos and didn't have a game yet, I had no idea what is good about a puzzle, and I started planninf some tricks before I bought it that would make it hard. Unfortunately it turned out being a little finicky when I look back at it now, but back then I was really proud of it. About the walkthrough: maybe I'll add one of playthroughs from the comments in my description.
And yes, the lasers can be annoying, I wish there was a laser magnet that would make the laser hit the inlet first try if you are trying it the right, but unfortunately there isn't. Thank you for the feedback and thanks for playing! :D

Pt.3
...speaking of tedious, it's so annoying if you have to hit the exact laser angle again and again in order to being able to repeat an action, e.g. in the end in case you have to reposition the weighted & laser cube up at the glass platform.
Luckily I already knew the mechanics of hitting a laser cube inside a dropper , but hardly anybody who doesn't already know about it can even guess this...
Finally, how about a walkthrough video? I mean there are some in the comments, but it's always nice to have an official one linked at the description, especially if it's a chamber THAT confusing... Anyway, thanks for your effort, you did an incredible job, it's just overambitious imo.
In some way, I know what I'm talking about ^^

Pt.2
Generally, I very much like the visual design of the chamber!
Generally, I very much DISlike the way of hitting laser receivers in narrow angles, it just doesn't feel right (piston platform & opening the "moon" pedestral button). I as the player am experimenting until something works out. It's in the same way boring and unsatisfying. The idea with shooting the laser multiple times through the same portal(s) came by accident, I NEVER enjoy something like that.
Getting the weighted cube out of the rear room by shooting the laser from the other side / from inside is a good idea. Unfortunately you can't immediately see and barely hear the effect, so I had to do several turns which was just tedious!

I have mixed emotions on this. First of all I appreciate everything that is not front page shit but really hard to figure out. This one actually kept me motivated for about an hour(!); I as an experienced player, but obviously not a pro, am proud of having solved it with only looking at one hint (no.6 - which I was already assuming). BUT... unfortunately a cannot give a thumbs up because this puzzle is so weird in many ways that in my opinion it doesn't meet the requierements of a good Portal puzzle. It's nothing that is based on the rules of Portal, instead it uses several twisted mechanics which an average player can't even find. I saw them on my way through hundreds of community maps so I tried them out here, but I don't really like much of them :-( Just because it is possible it doesn't mean it's legit.
To be continued...

@hestia.is.bestia I don't agree with you at all.
The puzzle is certainly tricky. So I think "Hard" is fitting.
And Technically knowing all possible moves in a puzzle always makes it linear. Therefore I don't see this as decent criticism.
There is only one "obscure" move in the puzzle which introduces a tricky mechanic not everyone immediately realizes. The puzzle is not hoping for it not to be discovered. It is made to show this to people.
I think a bad way of making a puzzle hard is having an obvious solution which is either stupidly "hard" to execute or requires extreme precision.
So overall in my opinion this level isn't made "hard" in a bad way.
I think it has a tricky solution and requires thinking and is not unnecessarily frustrating, due to obvious solutions that aren't executeable - it can get frustrating because not figuring out the solution, though, which in retrospect would make it hard in the correct puzzle way though.

@RectorRocks Thanks for playing my map! :) I watched your playthough, and liked it! Sorry for the signage, but I didn't know how else I could've done that, with antlines it would've looked really weird.

Very finicky solution with unclear signage.
Playthrough Part 1
Playthrough Part 2

@lapicidas no, it's not possible to get in there, that's just an "OR" connection because I made this map without beemod, so I had to make a manual "OR" connection
I'm glad you liked it, thank you for playing it :D

Done. I like this map! Good brain-effort. Thumbs up.
At the end I grapped the companian cube, just for fun.
Attention Spoiler!! Screenshot of the solution at the end :

In your Top-View of the Chamber there is a dark room at the right side from the blue funnel. It seems there is a laser inside. Is it possible to get there, I cannot find a way.

Solved, the "puzzle" without referring to any hints. There was a lot of clutter with the angled panels and many signages which were missing or completely obscured. I can't say I liked any of the ideas used. Especially the last one. It really wasn't clever and just relied on a gimmicky usage of the cube dropper.

The puzzle's difficulty was killed by how linear it was. I would rate it very easy in terms of logical difficulty. Spawn cube 1, then spawn cube 2, then spawn cube 3, then spawn cube 4, then exit. That isn't a logical puzzle. "Very hard" is streching it. If knowing all the possible moves in a puzzle reduces the puzzle to linear steps of obvious moves then it isn't hard at all. Making obscure moves hoping that someone might not see them is not only the wrong way of making a puzzle difficult, it also makes the puzzle less fun. The fun part of any puzzle is figuring out the correct sequence of moves which would lead to a solution. It has nothing to do with finding obscube moves.

@bassi_man can you send it to me in a message?

I finaly did this map, just getting the right angel was hard and took time. Took a 2 printscreen if you want to see.

@dire.fcs I mean if you can figure out the puzzle, then the piston part is probably the easiest part, so it's not challenging to get it work, that's why I don't think it's a big deal if that part is solved in a different way, nothing map breaking

(... this is not a huge puzzle ...)

@ohh, yeah, but that's not something I think needs to be fixed, it's just a small thing in a huge puzzle :)

we can jump through the higher vertical portal in the wall (on piston room) to the floor ...

@dire.fcs how did you solve the test without using the piston platform? Did you break it somehow? If so, please let me know

Apologies for the wrong name - That would be my Tablet's over-enthusiastic Auto Correct for you! All sorted now

This is a well known clever trick (in the end part); the piston plateform is useless and the the 2nd room (with gel corridors is the best part).

@nockscitney I watched the video and liked it :)
By the way, you mispelled my name in the description

@nockscitney Sorry :P

Excellent map. Took me a while to get the first part but thought it was very clever. Then I got mega confused at the last part, but mainly because my chat was telling me things that confused me.

Blind Run : https://youtu.be/mrPry9QMd2k?t=16m20s

I know the regular solution already so I don't really need to

@Afro Melon™ Thank you for letting me know aboutt the issue, I think I managed to fix it if you want to give it another try this way.

Broke it https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=890577599

Screenshots. yay

That's what I thought.

Yes, it indeed is a game glitch, I've never heard of anything like that before, it sounds very weird

What I did was typing load in the console and then choosing a save that I thought I made while playing but what was really a test chamber in the original game. Thing is, it still said "Reflectional Mansion" and had your name on it. I beat the test chamber it gave me and I got the Evaluate and then it went to my next queue. This is probably a game glitch and not a test glitch.

@NRisdon612 I can't really imagine how that looks, can you explain? It sounds really odd
And this puzzle has a solution that's somewhat unique, so you need to do that in order for it to count as beating it (or if there's any unintended solution which isn't a bug like yours, I'll admit you beat it but I'll fix the chamber)

Somehow, during the puzzle, I managed to change the map to story mode while still making the game thing I was in the puzzle. I don't think beating this chamber counts, sadly.

If someone solves it, then type the solution as a spoiler, because otherwise I can't know it for sure if you really completed the map, or you just typed you solved it without actually having it solved!

solved it!

@Volian1 There's actually a way to solve it, it's just something a lot of people wouldn't think about, believe me, I playtested it at least 10 times to make sure everything goes smoothly :)

IMPOSSIBLE
