Interesting & different map. I like how it makes you look around and scan the whole place. The final sequence after you get the portal gun seemed a little unnecessary. Thanks for making!

This is a really great map my only critism is that gathering up the 3 cubes at the end was a little tedious.

The part a 3:13, I found a portaling glitch to reach that portion and never extended the light bridge like that. Probably better a grate than a light bridge to block me from dropping to that section. I totally forgot about the light bridge that points down to the autoportal (orange) object. Otherwise very challenging map.

Wow! Complex and challenging! Hard but worth it in the end.

Great map! Cheers!

YES! Finally I solved this chamber! (I used not hints. :D ) Though I think I got the last cube the way that was not intended.... Ah well. Nice job on this chamber. Love it.

I like the back tracking. Does more with less space instead of a completely linear map.

Thanks for your kind words. In terms of detail and design, I'd have to say that this is one of my best maps. In terms of playability though, it probably my worst. I'm glad to hear feedback like that from someone. So again, thank you.

Wow. I was able to get thru without any hints or v.w.t. I thought that this map was very well designed, and conveyed nearly the perfect atmosphere. Im overjoyed at not having someones idea of suitable music forced down my throat - thankyou for not putting me thru that. I hate singleportal maps because of non-improvisable solutions, poor timing bits and backtracking. This map does suffer from backtracking and awkward timing (due to being s-p, and that killed most of the atmosphere/took me out of the realm of Portal for me. It became a task. That was only slightly helped by getting full control later on. Im still giving it a thumbs up. and favouriting. I never know if anyone looks at commenter favourites, but this one is on my list purely on design - I dont think there is a better s-p map out there, and I hate all of them!!!. Thanks for making it... I think. Cheers.

Also posted on TWP, but thought you may not check your maps often. My solution.

With a bit of help I made it,lovely map.Thanks.

Cheers how bloody obvious,I must be having a bad brain day.LOL.

Think about it. There is a white ceiling behind it, and there is a timed button right over the Orange Portal that sends down a lght bridge. Use the Faith Plate after placing a Portal behind the Light Bridge and pressing the timed button.

Oh yes I looked up but it did not become clear.

I take it you didn't look up? >.> There is a light bridge above that platform. Once you see that it all becomes clear.

Gave up in the second chamber, could not figure how to get to the middle of it for the second button. I gave it a thumbs down because of frustration, I am looking for a challenge with a bit of fun, sadly I felt fun was missing whilst making a overly challenging map.

Thank you. I appreciate your kind words. :)

Maybe a little lengthy but certainly worth it. The concept of starting with a single portal device and then switching to the dual portal device partway through the test is something special.

From what I've seen here, and from your other tests, you're an excellent Portal 2 mapmaker.

It took me ages to finally sit and test this chamber. Wow. What a chamber. Great job!

I was fairly lost of where to go first. I'm not sure how you go about making it more obvious.

Great map. thanks for sharing, please check out my workshop if you would

Great overall, just a bit too much backtracking.

No, look above the middle platform you'll see a light bridge up there, shoot a portal behind it then activate the bridge that descends from the ceiling. Also there is a video for you to watch if you get stuck.

i.e. is it supposed to be not usable for actually walking on it?

Bloody hell... Loving the map so far but i got stuck - are you sure the light bridge descending from the ceiling is placed correctly? Because every time I try to walk on it i end up BENEATH it and can't use it to get to the middle platform in the adjacent chamber with water.

@Brits Thanks! :D I look forward to playing your single Portal map. Believe me when I say that it is not as easy as it seems to make test chambers with only one Portal. Also yes, that was the intended solution.

Also, sorry for the confusion. I made this map about a year before I had even thought up of Secondary Fire. xD

Amazing chamber! Love the puzzles with the single portal gun. (I kept pressing the right mouse button after the Secondary Fire maps.:P) I'm currently designing a chamber with the single portal gun as well, after playing your maps I guess it won't be easy:)
Maybe I did it wrong but after I'd got the two portal gun, I had to do the same thing again in the room where you find the second laser cube. Is this intended?
