Brilliant puzzle!

@StackSmasher789 Yep, that's fully intended. Great work solving this one, and very happy to hear you liked the music :D

VERY NICE. Loved the use of all elements! Not sure if intended, but in the end I had to walk up the light bridge into the tilted portal near the end and replace it with laser . I think this the first 4/10 (acc to your rating) puzzle that I managed to solve successfully. Love the music as well.

@zeo1337 This map has some slight design flaws, but it's fun to see that that final move that also stumped myself when making it, still works its magic :cozycrashfish: To answer your question: just aesthetics I guess, but I agree that it shouldn't have been like that. Also, that one surface is just for anti-trapping :]
zeo1337 23 Jan, 2024 @ 7:51am 
LOL okay the actual solution is really, really easy compared to that. Idk why I didn't realize that would work when I was already doing all the tricky moves.

Question: why is there a lauchable drop, despite there being no launches? Also the portal surface above the fizzler doesn't do anything.
zeo1337 23 Jan, 2024 @ 7:31am 
So I'm really close here, but stumped at the end. I found an unintended ending, tho lol

basically, i used linked floor portals to put the respawned laser cube on the bridge button, then a single reportal here: https://cs2bus.com/sharedfiles/filedetails/?id=3145767233 which allows me to easily finish the level.

@mr. Out Thanks for playing! I think I know which surface you are referencing; it's just there for anti-trapping :] Great work solving it! Glad you enjoyed it :cozycrashfish:
mr. Out 7 Jul, 2023 @ 12:31pm 
Unprecedented, one portal surface was of no use . :D As usualy, excelent puzzle with exelent atmosphere. Thank you.

I took a bit over 2 hours over the course of 2 days to complete this puzzle and I must say, I am so glad I stuck with it. To say that the solution was absolutely genius would be an understatement. This was the most difficult puzzle that I have solved yet it was also the best.
Mikeastro  [author] 7 Dec, 2021 @ 2:47pm 
@Aneonen Thanks! Glad you liked it. Perhaps you experienced a 'natural transformation' in between your two runs of the map I really tried to turn this into an actually funny maths joke but eh xD
Aneonen 6 Dec, 2021 @ 7:41pm 
Very nice puzzle! The use of that angled panel as a bridge-only entrance was nice to discover.
My experiences with this puzzle haven't been isomorphic; when I originally played this one (maybe when it came out?) it was one of the hardest puzzles I had ever played; now with many more hours it felt much more manageable.
Mikeastro  [author] 7 Aug, 2021 @ 3:10am 
@nerdlingnation Thank you :D Excellent work solving it :cozycrashfish:

Fantastic puzzle.

I’m really pleased I’m not super smart and that my memory’s not as good as it used to be, because that means I can replay brilliant puzzles like this and still get that aha moment xD
Mikeastro  [author] 4 Oct, 2020 @ 3:19am 
@bullfrog Thanks a lot :D There are definitely a few tricky parts here
bullfrog 4 Oct, 2020 @ 1:37am 
Still an excellent puzzle and, just like last time, got to the same position, "then spent about 5 minutes or so just staring at the screen before the penny dropped!" xD
Teo 10 May, 2020 @ 11:39am 
Took a lot less time the second time around, really great puzzle
Mikeastro  [author] 8 Jan, 2020 @ 4:36pm 
@Rain Thanks for playing once more! How did you climb the wall? I thought the lights made that impossible... And did you also find a proper solution?
µ 8 Jan, 2020 @ 3:55pm 
Good Map! It was a little difficult as it was simple.
I could climb the wall at the exit using the light bridge...XD
It took about half an hour to figure out how.
Mikeastro  [author] 18 Sep, 2019 @ 6:00pm 
@Spider_Dawg Yeah, this one is very compact. And indeed, without that realisation solving the map would become quite impossible :P Anyways, thanks for playing once more!
Spider_Dawg 18 Sep, 2019 @ 5:23pm 
Another very fun, fairly short puzzle. I think what held me up the longest was not seeing that I could climb the inclined light bridge . I had dismissed that surface as one-way . Great job, per usual.
Mikeastro  [author] 12 Sep, 2019 @ 7:01am 
@BehindPortal Thanks for playing :D

@kimist108 The best moments in the game :]

Oh, the blessed ah-ha moment.

@可砸的六度双音 Thanks a lot for the video! Your solution was perfect :D Glad you liked it

Yeah, I really wasn't happy with the the way I did the end and then I got all in a muddle :(

@Requiemsoul Once more, thanks a lot! I'm glad you enjoyed this one too :]
Requiemsoul 20 Feb, 2019 @ 10:56am 
Amazing map. Pure lateral thinking and very satisfying to solve it as allways. Not easy one. I was stuck for a long time. Added to my favorites.

@lapicidas
I don't even really think about it, it's just the way I play. Sorry if that annoyed you. Still, thank you for the unexpected compliments!
lapicidas 14 Feb, 2019 @ 1:09pm 
@Leomievs
It is'nt funny or cool, believe me.
I know you, you are a very good player of portal 2. You are a master in intelligence and play skills.
You do not need that - believe me.
Mikeastro  [author] 13 Feb, 2019 @ 10:57pm 
@Turmoil Lol nice glitches :P Glad you liked it in the end
Turmoil 13 Feb, 2019 @ 3:07pm 
I did a speedrun of your map. https://youtu.be/-ePIZ8y8fxM?t=98

It was very satisfying getting back up after I was stuck solving the real solution. I especially liked the ending move.

Достойный тест! :okey::2018spacefox:
Mikeastro  [author] 2 Feb, 2019 @ 10:24am 
@asears16 Thank you very much! Your video was, once more, very interesting to watch :] I'm also glad you enjoyed the puzzle. I think the reason why the ending moves take most people a short while to spot is that you're sort of used to making optimal use of your portals, but here you actually have to wait for the right moment to shoot at the laser surface
asears16 1 Feb, 2019 @ 9:09pm 
Another enjoyable puzzle, Mike! Like with you, the ending moves also took me quite a while to work out. I think I was just overcomplicating, though. :P

@lapicidas
Lol I just find it to be more fun than just walking around I suppose, or maybe I really have undiagnosed ADHD??
jandlml 28 Jan, 2019 @ 5:47pm 
ha its probably just me
Mikeastro  [author] 28 Jan, 2019 @ 2:25am 
@jandlml Haha sorry, maybe I'm just really bad at estimating the difficulty of my puzzles :P I'm happy to hear that you liked it :D
jandlml 27 Jan, 2019 @ 9:07pm 
wow that was a great puzzle!! whenever you all grade your maps as not hard they always take me a long time to solve. this one is no exception. took me a long time to figure this one out. faved!!
Mikeastro  [author] 27 Jan, 2019 @ 3:51am 
@Atom Thank you very much :) And don't worry; I still have a lot of your maps sitting in my queue that I've yet to play :P
lapicidas 27 Jan, 2019 @ 12:03am 
@Leomievs What is the reason to jump around like an easter bunny on speed? There are some players doing that in their vids. ADHD ??

@Andi
Die beden unangedachten Lösungen von Dir sind genial :steamhappy: Daumen hoch!
Psychological Atom 26 Jan, 2019 @ 7:41pm 
Excellent map indeed! And I really like the music too. Sry if I haven't been making maps lately for you. But I will someday. I'm in a slump.
