[Coop] Discovery
I know and I have stated it in my posts above. Can we talk about the map now? 
(If it is fixed)
Six chambers of goodness, like a Colt 45. Mini campaign arranging 6 short maps in Clean, each virtually flawless and gravitating around Valve accessible difficult - which translates into easy-medium for beginners, and none-easy to practitioners. Only puzzles which stunned us for some minutes were the lightbridge and ball ones, requiring timed coordination.
We had a lot of fun on these maps (for a good >20 mins), which might seem banal to state but rare enough to surprise us when it happens. But we honestly marveled at the ending elevators not working, we supposed to be brought to the next map automatically.
They do work, it just take some time. I used instances Valve provided so the problem is probably in them.
E: Calculated and it takes 20-22 seconds.
And yeah, thanks for playing
I tried again with ss_map and it worked immediately. 
Not sure why, in coop we just stood there as when the start elevator bugs.
I tried it once with my friend and level changed. Otherwise I have tested in split screen mode and level have also changed (with that delay which is weird). I am testing now again and I also rename custom script I have to change maps so it uses the one in the .vpk.
E: Okay, so the map changes in ss_ mode. I also noticed that 2nd map is slightly older version. Newer one have tweaked visuals.
E2: Uploaded it. It doesn't change the gameplay so no really need to try it if you have beaten the map
I have played this just now with my brother. It was good enough except the last puzzle where millisecond-precision was required in order for the second player to catch the ball while flinging. Timed puzzles 
- noclipped. I hope that was not the solution and we just missed something.

108.1% done, -8.1% remaining...
Released here!
All maps for Portal (1/2) worth playing are mirrored here.
Just played them, really have nothing bad to say. Very well made and enjoyable. Will post videos of the play-through shortly.
- noclipped. I hope that was not the solution and we just missed something.There was no split-second precision required in the last one, at least how I did it.
Then I am looking forward to the walkthrough video

Not really walkthroughs, although they do obviously show the solutions, just in a needlessly long manner
