Cave's Caves
Wow O_o, I expected just the one testing sphere...
At first, I was pretty annoyed at the puzzles - great ideas, but awkwardly executed. The attention to detail really made up for that though, and I was pretty impressed with the voice acting 
It got a bit easier after that, but as the map kept opening up, I was loving just wandering around, seeing more of aperture and got that feeling of size and wonder I had playing P2 for the first time!
The 'secret' area of this map is bigger than most actual maps, and the whole thing is quite amazingly optimised, running smooth as hell on my old machine. Oh, and uhh I really liked the exit signs too - reminded me of Fallout New Vegas or Borderlands or something. I normally hate these fanfic style maps, but I loved this, thanks! If I had a vote, it would go to this. *clapclap*
I had the same trouble with the second chamber that Jepp had. SpAM_CAN, would you reveal the intended solution? To me it seems as if the solution relies on the very unpredictable behaviour of the bouncing cube - but maybe I'm missing the obvious.
I'll post a solution video when I get home tonight.

You don't have to jump and throw the box, but I like to :3
My review:
Do not read if you are judge!
Reading the other judge's comments after I have finished the map: I think I was the only who really understood and finished the first chamber. I think I spent the most time on the first chamber, and that was because I thought the button on the platform activated the speedgel and didn't notice the button right next to the speed gel dispenser... doh! You don't even need the bouncy wall at the start to complete the map, you can just jump through the blue gel dispenser out of a portal surface on the other side of the bouncy wall and bounce your way to the speed ramp victory slope.
How you get to the exit is you have to put white gel on the lift that brings you up, so then you can fling from the top platform down into it. The speed you gain is completely unrealistic (catapult).
I didn't like the next puzzle with the cube / gel. You had to raise the cube unnaturally high in order for it to fling correctly on the button and the way up to the top there I didn't find until 5 minutes into the test with lots of trial and error.
The next chamber with the cube and the funnel was a good concept, however pulling it off took multiple tries and I even quicksaved the game so then I didn't have to funnel the cube up to a specific spot every time it fizzled.
The last chamber where you had to funnel the cube on the buttons was again, trial and error; but it was definitely easier than the funnel cube puzzle previously.
It was a very good job on the voice acting even though you didn't actually sound anything like Cave Johnson, but it was definitely a nice touch. (this is the second voice acting included in a contest map 
, Vordwann did a good job too). The music and ambience were great as well.
There was also a bit of an exploring element in this map. Just before you start the chambers you can portal inside an office and take a small look around. The opened vitrified door however had nothing in it 
Its amazing you got this much done in 2 weeks, well done.
Damn, I didn't intend for people to portal into the office to begin with - that is for the left branch of the level when you disobey Cave. But thanks muchly for the review. I basically spent 2 weeks, 10AM to 2AM working on it to get it done in time =3
Cave was voiced by my friend, who sounds much closer to the original when I boost the bass and stuff, something I actually forgot to do this time around xD
Please post a video for the first chamber intended solution.
A lot of people got stuck there and your video in the 2nd chamber only. Thanks
No can do, I'm away again for a couple of days. I did record one earlier though and will edit it when I get home on Monday.
EDIT: ChickenMobile, did you try the left branch of the level too?
No, I did what Cave J said to do.
Alrighty. There's lots more stuff that way too, it doesn't just kill you or anything :3
