Going to test this when I get home.

Texturing 7/10
Aside from a few random texturing bugs, looked very nice indeed

Entity Placement 6/10
The crowbar at the start would have been nice and being able to see the monsters that lay just on the other side of the door would of helped a bit. Could have used more health packs and one bullsquid was stuck in the floor and had the ugly yellow blobs but otherwise well placed.

Design 9/10
Extremely well done. Adding extra areas for continuity and the overall layout for a 2D map was very good

Ambience 4/10
I've see this alot and I learnt from my mistakes. I start the level and can't hear anything but monsters! Lighting was nice which is why you got a 4 but sound is the other half of the score and there wasn't much of it.

Map Skill 8/10
Again, very well done. Aside from a couple of split faces the map was neat and smooth

Total 7/10 (4 stars)
A very good map that suits Flat-Life very well. Next time add a ".hl2d" file, you need them so when you press NEW GAME it goes to the lobby map where everybody can easily select your map!!! Duh! Read ChickenFist's instruction manual!!!

I thought everything was fine except what hlife_hotdot said about the sound... all you can hear is the reloading sound and monsters.

Very well done and fun. I think it was funny/good that you chose to make walking through the duct so you hear but not see gordon. The challenges were a little tough at the end--I had to godmode for the last bullsquid and the other big guy = )

Excellent job, fun map, win.

Architecture seemed fine. I liked the vent and the grunt ambush.
Low ammo at start. It wasnt enough to kill 2 bullsquids and the headcrab also there werent any medkits (or i couldnt find any). The boss was too easy..I just standed at the door and used the RPG. The boss could have been more creative. But i had to cheat in the area where there was a controller and a vortigaunt because of the special attack that controller does at close range is impossible to dodge.
So the gameplay was a bit boring for me. The map was too quite..no ambience.
However, the texturing was nicely done.
