And also: "come on, you were raised better than that!" ;)

As promised: intended solution ? Really good puzzle; definite thumbs up.

:) I've found "a [much] more elegant way" - I'll record and check.

Just read your reply to @macko68 (7 years ago!) so I'm pretty sure "the shot I made at 1:28" is unintended, so I will look for a more elegant way.

Good puzzle, but the shot I made at 1:28 in the following walkthrough I’m not sure about: intended solution ?

Haha, great to see people still playing my old maps. @lapicidas, your way is how I intended it, but @hub's way is cool too.

BTW, If I remember correctly I had an Easter egg in the original version where you could set fire to the dude in the observation room across from the exit with the laser. I can't even remember what I did in this version...

Nice easy map.

Clever little map, thumbs up!
I solved it a little differently than @hub: https://youtu.be/p1fBkPfun3s

LOL.
My first thought was "noob map, I can just portal bump" "owait" "ohh" "GENIOUS!!!!"
This map is exactly the difficulty I love. Perfect!

nice map, a bit of thinking to solve.

That is an intricate little puzzle. Thanks for creating.

@Brits and macko68:
Thanks for playing and leaving feedback! Yeah, that is unintended and I'm aware of it, but it's outside of the box enough for me to leave it in...Plus I already revised the map a ton thanks to sicklebrick at TWP repeatedly breaking it, and 'Id rather just leave it now so I can work on new stuff.

Well I did the same as Brits and was suprised that this version took me less then normal one (approx 10 min). Will be looking for other solution though

Forgot to mention, I love how the darker light and the music indicate that this test is harder than the non-challenge version.

I guess this is unintended: While standing on the cube, you can shoot a portal in that room, and bring the cube in there. Then I was able to open the exit the same way I solved the non-challenge version.

Have updated the map now to remove that exploit. Cheers for the feedback! I've been playing through your list - some fantastic maps on there.

The problem with my exploit (if you can call it that) is that it bypasses the most fun part of the solution. I think you could prevent it by only putting portal surface in the corner next to the lift, and narrowing the opening on that side.

Well, I think I've got it now: Resolution (challenge version) . It's worthy of my collection of Favorite Puzzle Maps . Perhaps it belongs in my hardest maps collection, but I think I was just being dense.

Ah, I see what you're doing there... I'll see if I can do something about that, although I'm not sure I'll be able to, given the design of the puzzle in general.

Oops, those images are backwards.

Leave the orange portal by the exit, then balance cube on edge of blue:
Part 1
Go through blue, and fire orange through the grate:
Part 2
This drops the fizzler so you can shoot blue into the second room.

KennKong - I can safely say that your way is totally unintended, and I wasn't aware that it was possible (I'd like to see it, if you have a pic or demo or something). There is a perfectly clean way to pass the chamber.

My solution included balancing a cube on the very edge of a portal . If this was intended, I must say it took all the fun out of it. Fiddly-twiddly solutions are almost as annoying as pointy-shooty bits. I'm actually hoping there was another way, so that I can try again and find a satisfying solution.
