. a few textures were misaligned, as was an overlay
. some lights were coming out of nowhere, others were too bright
. general look of the map is meh
but other than the looks of the map, I think it's mostly great. The chemical water thing was very cool, and I think you could take it further in your next map, but like people said, change the texture of the water if you can. also, you may want to have a sign other than the chemical sign, as it's kinda vague. maybe one that has symbols, like "chemical bottle" "+" "Bad water" "=" ":)"
the puzzles were cool, but I didnt like the 3 rocket turrets thing so much. also, there were some inconsistencies like the normal turret broke the glass, but later it cant break the other glass
Very cool. no offense, but I didnt think you had it in you to make such a nice map. I guess you proved me wrong.
I look forward to your next map, and try to work more on the look and have your own style of looks, that's very important. finding a balance between your style and having it fit into the portal universe is one of the most important things, IMO.
P.S. loved the cube talking at the end, and 3 rocket turrets locked on at the same time is possibly the worst sound in the world 




it never happened before. the room with the cube needs all three buttons (supposed to
)
