Pretty intricate puzzle. Took me a while to figure it out.
This is how I solved it after figuring out the solution: https://youtu.be/BDMSBNOZ-rk

一个新鲜的解密思路,也可能是我玩的比较少,见识短,如果用这个解密思路来做一个双人合作图,再加上需要互相交换门,估计会很有趣。

Good map. Good thing I turn off laser collision everytime I enter a map :-P
I also grabbed the cube through the fizzler.

I have never been able to aim a reflective cube while standing on a lightbridge. It is a technique I just cannot get!

Ooh, this is a clever one

Fun puzzle. Thanks!

Simply, but good. :steamthumbsup:

Oh the intended play was staring at you while you are facing toward the intended wall to grab and fizzle cube, fizzling is likely unintended.

This one is fun, middle to hard difficulty, maybe I just came off from the high of Mevious' map but it took me around 15 mins to figure out.

Hint: Reflective cubes alternates between here and other side of fizzler, the two big sections obviously
Consider to fix this with a hanging cage or island or something, reflecting an obtuse angle on a light bridge is hard, I fell off there often.

Excellent map! Pure logic and fun! Thanks!

Fantastic work! I'm pretty sure I solved it as intended. Really great map with a very simple layout. Huge thumbs up :]

Figuring out the logic wasn't that hard. The most infuriating part of it was Portal actually glitching out the cube and instadropping it below the light bride; also me getting hit by the laser in those tightrope maneuvers. Everything else was very fun and well thought out

This puzzle is really good. From reading the comments I think there are 3 possible solutions which all involve how you play from the beggining:

spoilers:

1 The fizzle cube solution, which makes you go on the bridge to the exit just on the start of the solution.
2 The take cube to middle room solution by walking with the bridge (which I assume is intended)
3 The solution (which I did) in which you walk with the cube, while constantly pointing it to the fizzler deactivator as you move, then getting the cube into the middle room and thus not getting it fizzled (which I did).

Very interesting chamber, I really liked it even though I'm not a huge fan of lasers. Tomorrow I'm also gonna try the redux and the "less logical" fan remake!

nice! required a surprising amount of activations

Nice little puzzle, I grabbed the cube through the fizzler too, at the beginning but wasn't really satisfied with that. I'm glad the intended solution doesn't involve that. Good work!

@ninjago00 Thank you! :D Cool username by the way

I really liked how this puzzle - and your other ones as well - was complicated without having a lot of pieces to juggle so that if you thought about it enough you could tell how the puzzle worked without it being a no-brainer.
Beb1 28 May, 2018 @ 5:16pm 
does the solution include pulling the cube through the fizzler at the beginning ? Very creative mechanic :D
le retardé 21 Apr, 2018 @ 11:34am 
@Demon Arisen I did try some of them before this one. You're one of the few puzzlemakers who make truly complex puzzles with few elements.
Demon Arisen  [author] 20 Apr, 2018 @ 11:21am 
@Adams McCall Thank you very much! Be sure to check out my other puzzles, I guarantee you'll enjoy them :D

Demon Arisen  [author] 4 Apr, 2017 @ 12:42pm 
@qrioso Thanks! Yeah this one's a little tricky in terms of balancing on the light bridge - but that's probably the most ninja move you'll ever have to do in one of my tests.
qrioso 4 Apr, 2017 @ 12:31pm 
Interesting one but not so simple, a bit trickier. I felt down a couple o f times trying to redirect the laser with the cube over the bridge. Good job
robertkjr3d 7 Feb, 2017 @ 9:12am 
Wow another super tricky one. I kept almost falling off the ladders. need railings. haha
Demon Arisen  [author] 6 Feb, 2017 @ 2:09pm 
@libbybapa Thank you! :) Yeah some people will definitely prefer this version, but the redux is a bit easier to do (and nicer looking). Thanks!
Demon Arisen  [author] 27 Dec, 2016 @ 4:48am 
@bullfrog Thanks! Yeah this one can be a little bit tightropey, but I've recently remade it so that the solution is a bit easier to execute, seems you've already played it actually http://cs2bus.com/sharedfiles/filedetails/?id=701540063
bullfrog 27 Dec, 2016 @ 12:20am 
Brilliant puzzle, I really enjoyed this one. Some of the moves are a bit 'tightropey' so I used F6 a lot, but, to my surprise, I didn't need any! Thanks
Donderbus 18 Nov, 2016 @ 2:33pm 
Very nice! I liked this one. Thumbs up :)
PixelPerfect 29 Sep, 2016 @ 3:17pm 
Solved it, but the puzzle is kinda frustrating for me.
Demon Arisen  [author] 10 Jul, 2016 @ 1:11am 
@GamerArtist2006 Nope, not impossible! Just difficult. Try some of my easier tests like A Nice Little Puzzle first. :)
PixelPerfect 9 Jul, 2016 @ 2:47pm 
Impssible!
SA_Zodia 6 May, 2016 @ 6:19am 
Nice

nice puzzle makes you say hmm

Very good map.
Demon Arisen  [author] 16 Nov, 2014 @ 5:16am 
@1980 Thanks very much! I'm really glad you liked it. My next chamber will be an advanced version of this one. :-D
1980 2 Nov, 2014 @ 3:32am 
Great puzzle! This was made in 2013. It took around 20 mins to solve. Fun & great!
jgaultney 27 Oct, 2014 @ 2:15pm 
Another great laser puzzle :) Thumbs up and favorited!!
Demon Arisen  [author] 15 Aug, 2014 @ 1:03pm 
@wildgoosespeeder Thanks, yeah that trapping thing does need a fix... Hmm... I reckon I'd better do a massive overhaul of all my chambers tomorrow and see what needs fixing...

You're right about the whole tightrope thing with the lightbridge.... Might add some elevated platforms to help with that. Thanks for the feedback! :)
wildgoosespeeder 11 Aug, 2014 @ 10:04pm 
Definitely a good one. My only gripe is that it can be like performing the maneuvers on a tightrope but can be done if you are careful enough. There is one trapping moment and that would be the platform below the exit that is behind the laser field. That needs addressing.

@Traveler807 Thanks, glad you enjoyed it! :D
Traveler807 8 Aug, 2014 @ 7:00am 
Very nice puzzle, liked it a lot:)

@contoor @pa1ntmaster @CodeWander @kimist108 Thanks everyone! :-D Sorry it took so long to get back to you...
komtur 8 Aug, 2014 @ 3:53am 
very good
The Sojourner 9 Jun, 2014 @ 10:51pm 
Nice little puzzle. Now to try the "Less Logic" variation....
CodePowered 24 Oct, 2013 @ 7:20am 
Challenging - that is what I really like in this map.
kimist108 7 Sep, 2013 @ 7:25pm 
Nice. Think I will try all of yours.
