Fuck me, this was a bastard of a test, and clearly I still haven't done everything... A few things I did felt unintended; will give descriptions below.
Lots of Spoilers in the comments
||Already covered the red room, so straight onto the blue:
The way I got into the funnel room seemed a bit ninja - I rode the funnel up to the top, fired a portal through the laser field at the far edge and quickly strafed to land back on the starting platform. Then I carefully stepped through and landed on the thin ledge below. The rest of what I did in there seemed pretty legit, though.
Green:
Actually found this the easiest part, probably because I played sicklebrick's previous map with the double bridge mechanic. Seeing where you're supposed to go was the hardest part, and to be honest the lighting and glass everywhere didn't really help matters. Still, relatively pain-free.
Central puzzle:
After a shiteload of trial and error, I decided that getting all of the cubes out was a good way to start. I eventually found what I think is the intended way to get a first cube into the central area - funneling it under the bridge with the portal surface lowered - though I managed to just carefully carry one out round the sides before doing that. The way I got the cubes out:
- Took the other two cubes to the red room with the funnel.
- Stacked them on the upper level so a connection could made with the upper receptor through portals.
- Funneled myself and the red cube up to the ledge.
- Connected the receptor, walked back and funneled myself over the partition to the blue room.
- Dropped the cube there, went back and fizzled the other two cubes.
- Back to the green room, reacquired the cube and took it outside using the method described above.
- Back to the blue room to pick up the final cube.
Then it was a matter of actually doing the central puzzle. From here on in was my favourite part of the map, as aside from a few fiddly cube placements it was almost pure logic. I'm pretty sure everything I did was as intended, as nothing felt forced or tricky. The only part of my solution I thought might be a little dodgy was the very end:

Had to actually use the portal itself as a lever to tip the cube, but I thought that was rather clever.
By the way, I absolutely loved this bit when it clicked:

Overall I was very impressed with how the elements of the previous puzzles were re-used in the central one.||
In a more general tone, I can honestly say I've not been this satisfied with myself for completing something since The Ledge, which is high praise indeed (that remains my all-time favourite map/mappack). The map is not without its frustrations; sometimes its quite difficult to see what's glass and what's not, and the fact that you don't actually need all of the elements at any one time adds some unwelcome complication to an already pretty-damn-tricky map. Still, that all seems like small potatoes compared with the intense smugness I feel with myself for having finished it, and indeed for the countless 'aha' moments over the course of my playthrough. So in short, I applaud you, good sir, for wasting my time in a most excellent fashion.
I also noticed this, by the way - some protruding models in the centre bit:


Playing v1.2 btw.
I must have been noclipping around too much the other day and accidentally triggered something that opened them? So without the doors open, even your bunny hopping idea wouldn't help, as we don't have any cubes yet. Nothing to fix after all.||
