Simple, but clean.

Great map, and was some-what challenging :)

Nice map. Not very hard.

Pretty good game. Had me going for awhile. Good job.

Nice map! Great fun.. And I am from MO. Show me how you do this map without the reverser. I am waiting...

Great job on this puzzle. Glad I came across it. Enjoyed playing and thanks for the hard work on it. Everything look real good. Thumbs up.

Gotta love those long-fall boots.

The reverser is like a safety blanket. It comforts you as you cross over to the daunting other side. In the end, you don't really need it, and the chamber isn't really any harder without using it, but it's a reassuring feeling to know you can go back any time you like.

yep u don't need to use reverse

Excellent Job of simple mechanics, but decent puzzle as well. Some commenters say they solved without the reverse, I am curious how. thanks
O'Brian 18 Jun, 2012 @ 12:24pm 
I didn't use the reverse.

Another map that got me thinking for a while, but not for too long, well done!
greyarea 5 Jun, 2012 @ 6:50am 
Fun, thanks. I didn't need the reverser at all.

Very good. Just the right level of difficulty.

Difficulty 4/10
Fun 5/10

Simple use of two way mechanics which is rarely used.
Pixerius 26 May, 2012 @ 4:43am 
Nice. But I did not have to use the button and change the direction of the tunel.

Yeah, didn't use the reverse funnel, so I don't think I solved it the way it was intended, and I feel the puzzle itself could have been a lot harder.
pnTn13 14 May, 2012 @ 1:39am 
Слишком просто. но тест хороший.
VinLAURiA 13 May, 2012 @ 4:35pm 
Well, that was fairly simple. I think I actually found yet another shortcut, though, because I didn't even need to reverse the funnel polarity. All you gotta do is shoot a portal through to the first chamber from the second while the fizzler is open and work from there.
Ichigo 13 May, 2012 @ 1:52am 
too easy :P
Gen. Crocket 11 May, 2012 @ 9:26pm 
Was thinking for a bit about it, then it was really obvious. Loved it.
Sh4rkill3r 11 May, 2012 @ 10:26am 
the tunnel is really slow.
Andicraft  [author] 11 May, 2012 @ 9:31am 
Uh, no. That takes just as long as just sticking the funnel on the floor and sucking yourself back with it - if not longer.
Sh4rkill3r 11 May, 2012 @ 8:18am 
Andicraft  [author] 11 May, 2012 @ 7:08am 
But not much faster.
Sh4rkill3r 11 May, 2012 @ 7:00am 
@Hideous no. without the revert button is more fast.
NaughtyTas 10 May, 2012 @ 5:49pm 
There's a lot I did not use, but anyway, clever chamber.
Andicraft  [author] 10 May, 2012 @ 2:26pm 
There are two ways to solve the puzzle. The reverse funnel button was the intended solution, but there's another one which is unintended, but takes just about the same effort/time, so it's fine.
NoriMori 10 May, 2012 @ 2:10pm 
Really enjoyed it. As others here have said, the button to reverse the excursion funnel is unnecessary. It only served to confuse me. Some people say they used it, but I can't imagine why they would need it, or how they would use it.
Sh4rkill3r 10 May, 2012 @ 10:17am 
i dont use the reverse button too.
Spicke 10 May, 2012 @ 9:10am 
i used the reverse button to solve it
Sir Wrexes 10 May, 2012 @ 6:40am 
Yup, the reverse button is quite useless, but the chamber was nice. I enjoyed it! :)
zaglis 10 May, 2012 @ 3:02am 
Weird. Did not need to use the reverse button and I honestly don't even know why would you need it.
sarge5160 9 May, 2012 @ 7:48pm 
I like it, pretty smooth solution. Good progression through it
Spicke 9 May, 2012 @ 10:17am 
the solvation is very hidden ;)
Wiggly Squish 9 May, 2012 @ 9:49am 
Ha! Very clever. I also used the reverse button and pulled myself through the hole back to the other side.
DemonicTunaFish 9 May, 2012 @ 8:02am 
You gave me a tumor. It was worth it.
SPACEBAR 9 May, 2012 @ 6:07am 
Thanks for the nice puzzle
Jens Klit 9 May, 2012 @ 5:33am 
I did it with the reverse beam, don't know how else to do even though a lot of people here say that you don't need it.
Stric_Matic 9 May, 2012 @ 3:20am 
The portal surface at the top of the stairs seems to be buggy - I literally had to shoot 10 times at it to finally open a portal on it. And I had to do it while jumping - if I was shooting at it while grounded it doesn't work.
pacifistchannel 9 May, 2012 @ 12:55am 
отлично!!!
YouKnow 8 May, 2012 @ 9:54pm 
I put a portal on top of the stairs in the left room and one right below it to fling myself up to the ledge in between the two rooms. Once I got there I shot a portal on the ground of the orther room and got the cube to the other room that way. I never used the button in the right room or the reverse pedestal in the left room. I think you should put another layer of grating on that ledge so you can't get up there or surrond the stiars with unportalable surfaces.

i had to use the reverse button and now that i have completed it.. it really should be called osmosis or diffusion... not meiosis or mitosis.... lol but this was fun. good job.
Yogi the bear, man 8 May, 2012 @ 9:03pm 
I had to use the reverse button
Wittlepup 8 May, 2012 @ 8:32pm 
Not sure why the retractor beam button is there. Still good chamber!
Optimus C 8 May, 2012 @ 8:32pm 
this should be called Meiosis not Mitosis.... Mitosis is the separation of two diploid sister chromatids of somatic cells where as meiosis is the zygote separation where two haploid gamete cells (n=16) fuse together and form a diploid chromosome (2n=32) which replicates itself and then separates via meiosis 1 and cytokinesis; then in meiosis 2 that's when the these repilicated diploid chromosomes form sister chromatids and separate. meiosis 2 is more like mitosis in retrospec.... anyways...
