Incredibly pleasant to figure out! Among my favorites of the collection

Semi-blindrun (at least 4 years since I've played, took a break starting from late 2019)

Difficulty: 3/10
Design: 10/10
Enjoyed: 7.25/10

Very clean and noticably harder than the previous ones. The second part was very straight foreward after having done the first.

I was almost giving up and looking up the solution. This was awesome.

Very clean.

I think I'm getting a bit better at this sort of map

The intended solution was amazing and super satisfying... bouncing the portals from floor to ceiling and flinging through multiple rooms in one fall felt great!

Good idea, but both chambers are far too easy to cheese

should have been two test chambers

absolute gem

When I got to Room 2, I knew that something was up with the other portal in Room 1. But then I saw that if I lose both my portals in Room 2, there will be no way to get back again. So I solved it the "intended" way.

I often exclude possible actions based on this, since I assume that tests are well made and there is no way to get yourself stuck, or that it requires speedrun techniques to do them. So if I see something I can do, and it requires strange movements like just falling past walls to get to a floor panel, I discard them, because they wouldn't be very elegant.

the whole second part was unnecessary, I just used the first pit again.

I'm almost certain I solved this test chamber wrong, but at least I didn't look up a tutorial and made some cool trick shots in the process... https://youtu.be/N9xomxNEUaw

great

This was very satisfying even though it defeated me completely. I had to use a walkthrough and even then I had to jot down notes! I hope you work for the NSA at least. Good job.

Nice puzzle, combining two cool portal 'tricks' in satisfying way

great map.very entertainment

First time around I thought I went the wrong way because the second puzzle looked exactly the same with one minor difference. Later, I fell behind one of the angled panels and trapped myself. Everyone playing this, don't do that! (LOL)

Very, very nice trick taking a Mevious technique to a new level, especially in the second part.

This was fun. Second room was almost the same puzzle, but with a bit of a twist. Very nice

I solved it the same way as Libbybapa.

Quite a few unnecessary portal surfaces. I didn't use a whole section of the map. Didn't even get the chance to explore it before I was at the open exit. Here's my blind run: https://youtu.be/8LUcTCrGzKE

Huh. Tried this around a year ago, and couldn't for the life of me figure out how to solve the last room. It was a breeze this time around.

good one, im getting better at keeping the portals straight

Great puzzle, I'm just not very good at it, but that's my problem, not yours ;)

Give me solution, please! Too hard for my little brain!

Good and well designed map. Very intuitive. Medium difficulty. Thanks for this one

Not sure why there's two puzzles that are the exact same here. Should just be one. Neat concept in any case.

amazing map

Great idea behind it, strangely I solved both rooms the same way which makes me think I skipped the "easy" way in the first chamber...
I managed to get a portal at the ceiling of the higher room, then came through that ceiling portal from the angled panel. That worked in both rooms.

Very smart. Bravo !

Wow, that was amazing. Subtraction *and* addition. Hint: use the long jump to blast through the ceiling of the short room, then step aside.

My solution

Brilliant, just brilliant!!!

I accidentally walked up one of the angled panels and fell behind it, where I was stuck and had to restart. This can happen in either of the two rooms. It's just a nit-pick, but that's never supposed to happen, especially in the top levels.

Also, gutschein is right. You could do as he suggests or take away some portalable ceiling panels.

very nice.
but you can solve the first chamber by placing a portal on the ceiling, without doing those momentum tricks. the glass wall that prevents the user from creating ceiling portals should be increased in size.

good thinking!

Loved this one Gig. Thanks!

Excellent brain exercise! So much better than angry whatevers.

nice, that had me thinkin there for a little while

awesome!

Awesome map again. Love it! Upvoted it after the first room because of its great concept. Now let's finish the rest of this map :D

There's a common theme throughout the "no elements" chambers, and thus the difficulty can't really get harder than medium (unless of course some crazy ninja/speedrunning skills are involved).

Today's equation is: 4 + 3 - 1 + 4 - 1 = 9 (but terminal velocity occurs at 7) .

In the first room, by crouching on the far corner of the landing at the top of the stairs, you can place a portal on the ceiling over the deep pit. This makes the solution to this room trivial, but without solving this room as intended, the second room is much more difficult. So, I would respectfully suggest that this short-cut be blocked.

Very cool concept, loving these no elements maps. Takes me a little while to figure out the trick sometimes, but I feel like Steven Hawking when I manage to solve them. Do you guys work for Valve? If not, you should. ;P

You get trapped if you walk behind the angled panels. Don't go back there!

Very cool. The second part wasn't much of an added complication, but the central trick is great.

I have finally learned how to logically think my way through these things. Works a lot better than running around, trying things and hoping I stumble on to the solution. It feels so good! Awesome map. Thanks Gig.

Cool as all the collection. Hint: 3+3 = ...
