I only played a part of this map for this time. I got stuck when returning to the beginning (the place where you cannot jam the door with the cube - I lol'd at that). Could you possibly give me some hint?
[spoiler]Go to the other end of the hallway, walk up to the vertical glass panels and look down.[/spoiler]

I had to noclip only one part - the one with the rotating platform, since it is impossible to reach the door in time (is there another solution when you don't have both portals?)
The timings at the "Combinations" part were very low, I had 5 unsuccessful tries and after I decided to give it up, suddendly I managed it. Damn, I hate those timings in maps

But that's just me and my humble opinion.
After all, this map is very nice, the atmosphere is great and the lighting and brushwork are all polished. Great work.
You should have plenty of time if you use the intended solutions. I understand your criticism though, i also hate timing puzzles which give you only half a second of tolerance. (The "stub your toe once along the way and you're too late" kind.

In the first room with the rotating portal gun, [spoiler]before pressing any button, work things out so that you are inside the chamber with the mesh window and the ball is on the two blocks in front of it. Wait for the orange portal to open in the other chamber, then get over there, push the button, get back and push the other button. The next stop for the orange portal is above the funnel. When it gets there, place a blue portal on the wall where the ball is and it will roll neatly into the funnel and to its destination.[/spoiler]
For the part with the rotating platform, [spoiler]press the right button first, wait five seconds, then press the left button and see what happens. This circuitry returns in the last part of the map, so make sure you understand how it works before moving on.[/spoiler]
