Easy solve but very tricky to pull off lol

Great challenge, very tricky

I FINALLY BEAT A MEVIOUS MAPPPPPPPPPPPPP

I fact it is very easy, but you first have think how (haha). Nice puzzle!
CoffeeCoder 6 Apr, 2022 @ 9:23am 
very different map that took a lot of thinking

Really clever map!!! Great idea! Thanks!

Took me a good while. It seemed impossible, then had an idea, then realized I needed to light up all laser receivers at once so it's impossible again, then I thought I might be able to juggle the lasers around so I can get up, get down, and set up the cubes without breaking the connection... I used the faith plate, having my doubts about whether or not this was "the good one" and I had finally found out the soution... And I did! It felt SO satisfying! Incredible.

Goddamn clever, as usual for Mevious maps. If my solution is right, this seems to require a very good understanding of how laser reflections really work in this game. You might first want to experiment a bunch to see what happens if you reflect different lasers from the same cube and such.

Very neat trick.

https://youtu.be/3V0Hit5sefQ Oh boy. After a couple of years without your brain nuts I needed a good amount of time to crack this. I first tried something crazy with the lensecubes hiting the light switch really fast, but the solution - as always - is simple elegant and very satisfying.

Thank you.

Still an excellent puzzle + I did it a bit quicker this time :)

Another great puzzle, Mevious. Glad you see you using all the different game mechanics, although I'm wondering where your chamber is with the white goop, seems like you could build a good one.

Finally figure out how to drop cube onto lower bridge while in exit area and am walking back to exit area with the cube and thinking, "OK, now what do I have to do?" I was actually surprised as stood in the exit area holding the cube and going, "wait a minute....I just solved it!":steamhappy: Awesome as always. Way to late to vote for Rexaura, but played it some time ago {after I finished Portal and before starting Portal 2) and enjoyed it immensely--that final chamber took many days of trying thing, failing, walking away, and then trying again...

brilliant!
Calwin 1 Sep, 2019 @ 7:09am 
excellent concept!
Sophronius 28 Aug, 2019 @ 1:18pm 
great map, that really took some thought to solve
SCHMUTZyyy 9 Jul, 2019 @ 9:23am 
excellent brainfuck

Such a good puzzle. Thanks!!!
Arkushet 8 Mar, 2019 @ 9:33pm 
Now that was a brainteaser! Took a good fifteen minutes to figure out the setup I needed and then another ten to figure out how to execute it without the first bridge shutting off when I go through the emancipation grill . Excellent map!

Thank you for a great map. The best maps seem impossible but persistence is all that's needed. :)

Loved the "this can't be done" feeling as it makes the solution much more satisfying.
tapmage 21 Nov, 2018 @ 12:21am 
Whoa those lasers got tricky but solved it in 10 or 15 min. It was fun.
Lloyd.Edwards00 7 Nov, 2018 @ 3:44pm 
the name is accurate
bachwiz18 15 Nov, 2017 @ 8:05pm 
Awesome map! I figured out the ending setup within the first five minutes, but I still spent a good 45 min trying to figure out how to get there! Excellent use of laser bootstrapping .
☢Personal★Fronk☢ 24 Oct, 2017 @ 1:35pm 
Wow! great map!
XYHC 21 Oct, 2017 @ 2:29pm 
Beautiful! A very-well made logical chamber!!!
bullfrog 11 Sep, 2017 @ 2:36am 
Superb puzzle. I’ve been stuck on this one for some time. I even checked the first part of the walkthrough to see if how I had it set up was correct and it was. I am sooo pleased that I didn’t give up and look at the rest of the walkthrough, because when the solution finally dawned on me it was brilliant – thumbs up and added to favourites. BTW; re @[SKILL]CAMP’s comment below: the correct solution requires no “tricky alig(n)ment” and is definitely not “ based on c ah (ha)nce”!
Master.AKA 14 Aug, 2017 @ 1:10pm 
Beautiful : ) I solved it before and then Downloaded again by accident! Beautiful : )
Artmugal 11 Jun, 2017 @ 6:52am 
It's not a puzzle but just tricky aligment, not very clever, based on cahnce.
jandlml 19 May, 2017 @ 6:35pm 
excellent loved it!
EndOfPortal 31 Mar, 2017 @ 3:44pm 
Exellent map but this time it was really tricky !
z34chris 30 Mar, 2017 @ 9:36pm 
I like playing this map later, all i can remember is set, latch and complete
snowhog 20 Jan, 2017 @ 10:17pm 
A nicely done chamber. Enjoyed it.
Lihoman 24 Dec, 2016 @ 9:42pm 
Великолепно!
LPChip 12 Dec, 2016 @ 10:13am 
Awesome puzzle, and yay for finally solving one of your tests since years. (yes, they're usually above my skill level)
Donderbus 28 Nov, 2016 @ 1:29pm 
nice one, thanks.
Mr Vapour Waterhandle 20 Nov, 2016 @ 1:14pm 
Really cool concept, and took a satisfying amount of thinking. I'm glad to see more new concepts in your puzzles as opposed to another funnel/light bridge puzzel. Nothing inherently wrong with them, but I like things I haven't seen before. Great job once again!
club 17 Oct, 2016 @ 2:03am 
Amazingly satisfying
PixelPerfect 21 Sep, 2016 @ 2:28pm 
Thumbs up and Favorited.

это что-то! ОТЛИЧНО!!!
zigzagtenniscoe 1 Sep, 2016 @ 3:56pm 
Clever and fun as always. Difficulty intermediate. Continue the good work.
PixelPerfect 20 Aug, 2016 @ 12:56pm 
How in the world did you come up with this stuff?:steamfacepalm:
dan 2 Jul, 2016 @ 8:30pm 
Very good! You're the best!
h 16 May, 2016 @ 7:56am 
Wasn't too difficult, but it still made me think.
z34chris 7 May, 2016 @ 8:14am 
good job, crazy set-latch-hold trick with the laser beams :)
LUCA-86-ITA 26 Apr, 2016 @ 5:08pm 
Good job the map 100% works!!!!! :steamhappy:
TORRENTE 26 Apr, 2016 @ 5:25am 
Another cool chamber! Tx Mevious!
MmmmmmhHHHhhhhhhmmmm 31 Mar, 2016 @ 10:01am 
I pretty much just bruteforced my way through this one. I just tinkered with the portals and cubes 'till it clicked.
