I added my comments in the video; I highly recommend watching it. Sorry the voice volume is a bit messed up. 
All in all a rather good map but the timing in the last part is ridiculously short.
I spent about 15 minutes trying to hit the sensor using the non-obvious portable surface and had to use that insane tiny tolerance. I did not end up needing the lower corner of the square portal but I was just barely within the portal and it was quite a chore.
The last part still eludes me because I simply CANNOT make that in 6 seconds. Also about 95% of the time I do not shoot the portal in the EXACT correct position to light the laser catcher. The 5% of the time that I do shoot it right on the money . . . then when I reach the door . . . it closes in my face and snips my nose off. I need 7 seconds !! Not 6 !!
BTW - how do you quickly RUN forward as you did at one point in your Video ??
