It's a combination of testing elements, environments, and the solution is using a combination of testing elements. This map is a bit on the intermediate level. Experienced players will have a less difficult time on this. This map was made to have the player explore non-testing areas, which is required to exit the level.

nice map, but there were some parts that really annoyed me:
You have to jump to get into the funnel
Why was atlas there?!
My radio got fizzled =( (the music continued, so noclipped for a second to see if it was still somewhere around but it wasn't.
The blue gel puzzle was quite nice, but water would be great!
The fact that I had blue gel on a part made it annoying for me

Yeah, the map was made to be annoying, but satisfying after completing a puzzle.
Atlas was in the Employee Lounge because he wanted a "I Need a Hug" Coffee Mug. Take a look at the cup that's in front of him on the table.

I liked the map very much, however I had a really hard time with the gel and light bridge.
it seemed like I needed more gel on the end of the bridge and just could not get it there. I kept bouncing over the bridge - also in that room the gel dispenser looked like a cube dispenser - other than that it was very clever and thoughtful. I did enjoy seeing Atlas on my travels - Thanks and keep up the good work!

For those struggling to get through the gel part: the way you jump toward the gel affects the bounce. Don't be afraid to jump off away from the edge into a blue painted wall.
There also may be an alt. way of getting through the blue gel room.

Excellent map. Liked the co-op partner in the back room. Thanks for creating.

Alt gel bounce spoiler moved portal along painted wall and painted bridge to the end and then bounced once from bridge to wall to exit

Ha! That's one other way. Not the way I found, but I designed the blue gel room to be flexible for the player so different solutions could be made.

I'm playing custom maps and record my first time of playing them. So the run is not perfect and may not use only intended ways, but maybe it can let you see how other people may understand the map or you could just enjoy someone playing this map for entertainment.
Anyways, here is the recording:

I solved the first room by placing the cube on the edge next to the light bridge button. Didn't even know that the door by the turret can be opened. The second chamber I solved without using vertical light bridge.

Uh... How did you solve the first room without opening the door? It's impossible to get to the other side without opening it.

Definitely not impossible:

Wow, I'm glad I choose to make the fizzler emitter static and not dynamic. Nice find!

Interesting map! I loved the atlas thing .

It would be a better map if it had more portaleable surfaces in the chambers, as I found it pretty straight-forward. But nice overall

Blind playtest:

P.D: I screwed at the end (a lot) and I was lucky as I got the funnel before seeing I had to use it (Actually was trying to somehow "break" the map)

For those that try to cut down on using Portals, the first observation room can be accessed without using portals by grabbing a chair inside the observation room and standing on in outside and crawling where the glass is broken. I'll post my record later.

Nice! I thought about that, but I didn't think about grabbing the chair. I was going to smuggle the cube past the fizzler (it's possible since you can shoot above the fizzler), but that didn't save any portals.

I wish I knew how to insert the Challenge Mode for my maps.

Yeah. I'm really hoping that when they release that simplified puzzle creator that they allow custom maps to integrate with their challenge mode stuff/store records on their servers/etc.

Something else to point out, Atlas's cup on the table has something funny written on it.

This was, simply put, one of the best maps I have seen yet. Bravo.

I guess the accessible observation rooms idea will be kept on my "good ideas" list.

This was a great map, which I enjoyed playing the different ideas involved. They were a good difficulty too. My only complaint (only minor) is that the smashed observation windows don't go with the clean theme that well in my opinion.

Keep up the good work!

I'm glad to hear your opinion. On some of my maps in development, I've been trying to make observation rooms accessible. I realize that broken glass may somewhat clash with the clean theme. But that's the price to pay in making a different kind of puzzle. I'm also glad to hear that the difficultly was fair also.

Have you thought about going with destroyed theme?

Yeah, I tried that out a few times and compared it to the Official maps, but I didn't get anywhere near good. I'm sticking with what I can do. I may give another crack at in in my MapPack that I'm working on.

A fun combination of testing elements. I went ahead and gave it a 5/5.

Little Complaints
I had some trouble putting the laser through the box under the light bridge; the box could wobble to either side. I'm not absolutely sure this was the intended method, but using the bridge to stop the box sure looks like what you had in mind.

I did not use the light bridge with gel.

I really liked the trick at the end.

Well, having the box under the bridge is one way of doing it. Depending on where you placed the Portal with the Hard Light Bridge, you could also stand on the bridge and set the Redirection Cube on the bridge and redirect the laser to the catcher.
As for the blue gel chamber, there are at least 3 ways of solving it.

This map makes good reuse of its elements, including the rooms themselves. I didn't need the lightbridge in the gel room, but when you allow blue gel to be funneled all over the place, there will be alternate solutions galore. I enjoyed playing it. 4/5 from me.

just to annoy people u could add a cubebutton right in front of the elevator door... because its possible to bring the cube till the end

Great map! Love the way you incorporate the office-spaces into the puzzles. Gives the map a feeling that Aperture Scientists really worked there!

Btw, also solved the second puzzle without the lightbridge (Had not even noticed it, saw it on this forum first..)

Heh, it's been a few months since I last heard anything about this map. You may like the Halloween Tricks map I made in October. I'm glad you enjoyed it!
