I'm going through all of the maps that I played for the contest and post my rating and comments.
It may be a bit out of date if you have updated your map since then, but hopefully it's useful feedback nonetheless.

[spoiler]As noted by the author in the description, there are quite a few bugs, both visually and gameplay-wise. This is very unfortunate, as the map would definitely have gotten a higher score if not for those.

Aesthetics: 3
Apart from the aforementioned bugs (areaportal, texture misalignments, cube maps) the visual design is pretty good. I like the use of the "desolation" soundtrack from the original Portal. The mix between clean and destroyed / reconstructing is done well; there are no jarring transitions.

I personally think the purple colour of the smoke compression field clashes with the overall theme, but that's not the author's fault. (The texture is part of FourthReaper's custom fizzler pack and its function is associated with that colour. Changing it would be inconsistent and confusing.)

Gameplay: 3
Nice puzzles, but the various bugs require some pretending/cheating in order to complete them. After switching the purple field in the second test once, the player clip layer started working in reverse for me. (It was on while the field was off.) Also, the cube dropper in the final test didn't work, and the rotating wall panel started in the deployed state.

Difficulty: 5
Suitably easy for introducing this new testing element, so no problem there.

Overall, this will be a great map once the bugs are ironed out. Too bad it's too late for the contest.

Personal score: 4[/spoiler]
I sincerely hope that you keep working on this one!
