very easy puzzle, but why is there a reflector cube?

Tricky. :steamthumbsup:

Nice puzzle

Simple looking chamber which became harder by the minute XD ...until I finally found a way to manage the funnel from the exit. Thanks for creating :-)

Still took me a minute to figure out that setup. Nice puzzle

Nice puzzle!Though every element is familiar enough,I almost had no idea at all when I started.I also agree with @Mikeastro objective comment,but I was stuck for a long time to figure out how to use the reversal funnel……sadly……

Very nice map. I'd say easy/medium instead of medium/hard. Good hammer work. Big thumbs up

Fantastic puzzle. Quite challenging, took me a while to figure out. Nice hammer work too. Thumbs up and added to favorites.

Very nice map. Seems like LB has beaten me to posting the link to my video. Even looking at the comments I didn't really get any hints and was still fumbling around like a baffoon, until finally I saw what I was missing. Unlike LB, I don't consider myself bad with funnel, I was just blinded in this case :)

I'm bad with funnels and this map really highlighted that for me. Here's my blind playthrough: https://youtu.be/TIZbHIwseS0

Nock also had a heck of a time with it: https://youtu.be/6dQw9K7BHUA

Great puzzle. I did it slightly differently to the walkthrough, but the important bit were the same.

Just found this map. Had fun getting through it. Solved it almost the same as Mr.Narrator.

Great one.

As soon as I solved it, instant favorite. GREAT puzzle design.

It's too bad that maps like this are not in Top Rated All Time.

Damn that's a hard chamber!! I love it!

Hint for anyone else that was as clueless as I was - box next to the reversing button . Thanks YUKI_67.

This is really really hard, still havent solved it yet... I feel stupid, but that means you are doing a great job, keep it up!
Andi 20 Jun, 2014 @ 5:01pm 
Brillant. I was stuck for a long time but I managed to escape, thumbs up.

Nice visuals, nice puzzle !

DISCLAIMER:
Read my profile before reading the rest of my comment!

It's a clever solution but I feel that a warm-up area to get the player used to pushing cubes with the funnel to solve the test would be a good idea. A button-activated piston platform with excursion funnel to push the cube onto the button to the exit may help some for a first area and have the main test be the second area. The laser fields may be too daunting when first entering the chamber (as of v1.3).

Thanks yuki! only videos i could find on youtube had another button type for the death rays and a sped up 4 minute blind playthrough! yours is solution with correct button type
The Sojourner 26 Mar, 2014 @ 9:47pm 
Slowly but surely, the solution dawned on me. It seems tricky because a key portalable surface isn't marked.

Excellent work!
YUKI_67 23 Mar, 2014 @ 1:22pm 
I just saw your walkthrough, very nice map.
YUKI_67 23 Mar, 2014 @ 1:12pm 
Here is my solution : http://youtu.be/t43uYXoiW3s
I guess this is the planned solution ?

SO DAMN COOL!
Rector 16 Mar, 2014 @ 5:20am 
I saw the intended solution after I recorded my playthrough and it was amazing! Too bad I didn't solve it that way :/
Rector 16 Mar, 2014 @ 12:50am 
Visuals were awesome but I broke the puzzle
Here's my (sped-up) playthrough because its slow:

Thumbs up! Thanks for mapping!
Cheers! :)

Great puzzle, so clever, so good!!

Both cubes can be reached through the laserfield from the cube button.
Sir P. P. Camelot 14 Mar, 2014 @ 10:45pm 
I'm weird person) Fix your map, it's pretty good.

WTF? Whenever I step on the button, the fizzler becomes invisible through that piece of glass.

Nice one! Cheers!!!

@Mr. Narrator: You won't be able to pass through the exit door unless the solution is intended. Can you tell me how you solved it?
Sir P. P. Camelot 13 Mar, 2014 @ 11:51am 
I am not sure my solution was intended. Any "official" walkthrough? And I could not pass through the exit door(
ken.roberts 13 Mar, 2014 @ 5:01am 
You say "medium-difficulty" - but I have been stuck since yesterday.
Gotta be something simple such as using the Orange funnel instead of Blue - but I am simply NOT seeing it yet. So I love it. The harder the better.
Requiemsoul 12 Mar, 2014 @ 3:28pm 
Fantastic, nice and very clever puzzle! It isn´t easy!. Well done!
kiwi 31 12 Mar, 2014 @ 2:13pm 
je n'ai pas trouvé la solution... si il y en a une
