This duck, kicks ass! Deserves every one of 24K upvotes and more. Makes me actually loose weight. Did it all with no walkthrough video cheating glenmcd[AUS], OK? :))

getting the cube was the only thing I could do without the walkthrough

I was having a good time until this stupid ending.

Nice work, could be an official Portal 2 Map^^

I too did not see the portalable surface seing into place under the gel dropper . When I finally did see it, the exit options became much clearer. Enjoyed.

That was a big think

Music also appeared in Portal: Prelude, so you could check the files of that.

Great puzzle

what is the music at the start
Čolibri 29 Apr, 2019 @ 11:13am 
Good flight puzzle.

very well done!

The first time I tried to fling to the end it failed completely for some reason.

I was trying to exit the chamber without using the repulsion gel and failed miserably. 5/7 will fail again

The end is good. I thought that I would drown. But I was fried. Thanks

Hopefully quicksave exists... Great map btw

Stupid map!

Enjoyed solving this. Cosmogony Episode3 looks and sounds good. Less walking, more thinking and another great Portal experience. Good puzzle that seems easy but offers a challenge. Restart is easy as level is short. Good work. :steamhappy:

EXCELLENT

having a really hard time with this one. I know what to do. it's just too finicky. also found a glitch. when I fell with the cube to launch, I somehow ended up landing in the liquid to the left of the bridge at the bottom. and when it respawned me, it was always directly above the liquid. I was stuck in a death loop.. great level otherwise. I'm a fan of yours
thompson004 17 Aug, 2017 @ 4:47pm 
very satisfying.

Nice map, well made and sufficiently lit. Again I missed any "secrets" in this map but was able to solve the exit room puzzle. I got the cube where it needed to be on the first try and myself out the exit on my second try (the first only failed due to a badly placed portal). I attribute my success more to a well laid out chamber than anything else, it must have taken a while to get everything where it needed to be to make that jump work as perfectly as it does. Great visuals with attention to detail again, on to the next one. Thanks for your efforts.

could not get the cube on the button, I knew how but it was annoying when I messed up and had to do it again and again
式微 17 Jan, 2017 @ 7:41am 
how difficulty....
mobsta Lobsta 9 Jan, 2017 @ 8:39pm 
thank you for making this. it was a nice level of difficulty
Perfect Rank 4 Jan, 2017 @ 9:06pm 
That cube and button test...
Me 21 Nov, 2016 @ 4:36am 
Pretty easy................................once you know it.
bluemime86 17 Nov, 2016 @ 3:34pm 
in the part where im trying to get the cube to the button, the dreaded auto save happens when i am falling into the lasers. So now i have to start all over again because of the flawed autosave
Petutski 17 Oct, 2016 @ 3:23pm 
Played again after 2 years. Experience really does make a difference. Great map!
mood3rd 13 Jun, 2016 @ 1:53pm 
good map / puzzle.
solution to getting cube on the button, was not obvious.
as it would mostly fail, in the basic editor. & with real world physics.
a funel on the ceiling, going to the button, would remove it's obscurity,
& enable real world logic, to florish.
died once, when trying to exit. (not aware of the panel ?)
saying that. it did not take long to solve.
the map design / limited options & items helped a great deal.
fun had :)
NorthGoneSouth 4 Jun, 2016 @ 7:36pm 
So I figured this one out pretty quickly. Then I accidently put the blue gel in the wrong place and it made my life hell... -_-
Xorven 16 May, 2016 @ 12:53pm 
There is my favourite Portal: Prelude music, thank you so much ! :D
dv8skp 30 Apr, 2016 @ 8:44am 
That was so much fun
Tygron 19 Mar, 2016 @ 8:43am 
verry nice. I wonder about the music on the start of part 3: where did you found the song?
The Mage 1 Mar, 2016 @ 1:38pm 
Tricky ... very nice!
GARBENJERMAX 12 Feb, 2016 @ 9:05am 
see the easter egg g_man?!!
i was scared! xD
z34chris 19 Dec, 2015 @ 6:40pm 
little funky but i figured it out
rAge 27 Nov, 2015 @ 11:42pm 
stucked at the red laser for several minutes, then I realized I have to "fly in"the cube.
and then the design of jumping on the gel is good, but not so obvious.
Rx 16 Aug, 2015 @ 7:47am 
God map
zagan 28 Jul, 2015 @ 7:03am 
worst map I've ever played, how is flinging the cube fun ? I need more than 20 tries before the cube land exactly right on the button, that's not a puzzle anymore it's just frustrating, particularly since whan you miss you need to go back for a new cube.
Fractal Pterodactyl 15 Jun, 2015 @ 7:08pm 
It was a decently difficult chamber :3
PortalFan 16 May, 2015 @ 3:27am 
It is one of the hardest map I ever played. Very good work. Thanks !
