The solution is always most obvious to the designer. The first room cube trick is not obvious and although devious, is not fun for this player. I had to look in here for hints to get through and when that happens on first room it's not usually good. The rest of the puzzles were quite good though and on the plus side, I'll remember the effect of vacuum on cube trajectory in future.

Nicely designed, however, I did not like the trick with the cube, it is totally unexpected.

Really clever map! Thanks!

great job, it took me awhile to figure out the second part, fun map, thanks for creating!

Interesting puzzle. Glad it didn't had android hell spam.

nice one

I found a glitch. The cube takes you inside the vent and you have to stand on the cube to go inside.

That was fun and amazing. Thanks!

The cube fly in the first room was impossible to predict. I only got it by accident.

Like, dude, this chamber is amazing!!! The first room totally got me, and the last room took me quite a while to figure out, but man that was fun!

New mechanic nice

Nicely done! Took a little thought to get through the last room, trying to get the pieces done in the right order!

how did you figure out that the cube would fly in that direction. very cool!!

Smart.

I only solved the first chamber 'cause I tried to destroy the cube lol.

There were some slightly annoying elements that made it harder than -I think- was intended. Fun map. Perfectly challenging.

Nice map, very original. Took me a while to figure out.

Nice map! Unique and fun! Thanks!

good map
I struggled in the 1st, as not noticing the cross, I dispensed with 3 of the turrets using the floor.
(4th by hand)
due to this.
did not get, how to get the cube over the fizzler, for a while.
when I noticed the cross & later, past the fizzler, the delay.
it all fell into place.
the last was hard also.
because I did not see what the pedestal button, was doing.
so did not understand, for a while, why the cube was going there.
it seemed ilogical, & broken.
so larger cross & better visual of pedestal button effect, would be a good update (for me).
or a guide dog & white stick :)
map logical / imaginative / fun (for sighted people)
thumbs up

I liked how you had to use the vent to make the cube arc upwards over the fizzler in the first part, and how there was a button that changed the cube's path in the vent in the second part.

I guess it's a feature but momentum seems a little wonky here; not sure how much those cubes are supposed to mass vs. a turret etc...

Is that a bug or a feature? Not how I expected the mechanic to work....

lol, that flying cube, i think its just the funniest thing. XD Still fairly simple as far as tests go, but its laid out well and looks good too, on to the last one. 7.5/10

Original with good puzzles. Great work !

O.K.

O.K.

Very cool. Good series :)

Awesome. I love this series so far. Great job.

Really terrific. More please!!!

Enjoyed.

Most clever. I am not convinced that the turrets performed any important puzzle element, other than annoyance. They felt shoehorned.

Absolutely brilliant. A bit too short though, I hope I'll see more of it!

Dat prerecorded message:D

Awesome puzzle. Very funny. Thanks.

Turrets highly explosive. Handle with care

Very cool, and I know I'm a little behind on working through the popular maps, but I love that someone was able to 'restore' the pneumatic tubes. I actually strongly prefer them to the goo.

It took me a while to realize that the button under the 2-ended tube was there to 'redirect' it downward or outward. There's no symbology for that, and the lack of particle effects at the 2nd tube doesn't make it easier. If I hadn't seen the e3 demo a dozen times (wherin a 'training' chamber shows the turret dropping on the button from a 2-ended tube), I might not have ever understood that. You also can't see the laser grid or door from that most important button, and there's no puzzle-related reason for that.

It could use a little tightening, is all, for those without a lot of external portal 2 experience. But it's easy to be critical - this is a great little series of maps, and thanks again for restoring this mechanic.

awesome map :) Took a little time, but the solution was worth it!! ;)

Increible!!! Eres un genio, me han encantado tanto estas como las otras tres, espero que sigas haciendo mas.

woow pretty good. well done

My solution: http://youtu.be/fmz1gKMdfGE

The laser field in the last test of this map is buggy. Even though when I press the big button, the laser field sometimes doesn't disable, or looks like it doesn't disable. It might have to do with accidental multiple presses when placing the cube on that button.

Very clever design. Took me a while to figure out the last room, in the most satisfying way.

OH Yea I figured that out "Hooah. I liked that a lot. I did keep messing up tho, had to do it over like 4 times. But I knew that Pedestal button was for something.. HeHe :) Thanks for the fun.

I don't know how you did this but when i did this, I tried to figure it out. I managed to do it by accident not knowing it. Then I tried it on the X. When i saw that, it made shit my pants literally. You sir are a genius and the people at Valve should worship you for thinking of such a maneuver.

THIS is a very satisfying chamber! The last room was especially challenging. The usage of the vents is just outstanding and Valve should take notice of this for their next game. Excellent job NK!

Excellent! No problems here except one time the cube didn't land on the button quite right after it came out of the dropper. No big deal.

Amazing mechanism!

Okay, I don't understand, where you can get trapped? I would like to fix it, but I'm almost sure that you can't trap yourself - and if, you'll be exempt. Sbd screenshot or better description? ^^

I glitched the laser feild so i had to restart that level i hope he fixes that also how to glitch it is to quikly move the box n fast.

this was awesome i hope you make more parts....

absolutely brilliant! :)

I really loved the first chamber's solution, but I'm still trying to figure out the second one. :D
