I'm playing custom maps and record my first time of playing them. So the run is not perfect and may not use only intended ways, but maybe it can let you see how other people may understand the map or you could just enjoy someone playing this map for entertainment.
Anyways, here is the recording:

Also note the video description for more feedback and my signature for additional project information.

I really thought that the test chamber was broken, but we realised you had to do some fling replace portals quickly trick to get both players across in the end (looking at the playthrough). We thought we could place both portals on the white surface together to get both players across but it was too skinny. Sigh*
Nice job anyway. They were difficult puzzles and the first chamber eventually sorted itself out. Nice

Really really good map but you absolutley ruined it with the way you had to get the players out of the last room. I was stunned in disbelief that that was the solution. It was such a good map before that; near retail quality. But that ending needs fixing. It tainted this near perfect map.

4/5

I'll improve the 2nd chamber "end" as soon as I get back to my computer. Probably going to add something new there as well and improve detailing.

Well, I just played it through for the first time:

Evidently the ending hasn't been improved. Good otherwise, though.

I have been quite busy last couple weeks and my motivation for mapping have been quite low. I'll try to push out an update eventually.

E: Uploaded a new version which have a ramp in the last chamber for easier exit.

You've got some bugs in your map

Just want to note that the site I was redirected to for download was identified as having malicious software on it. Most likely it has nothing to do with your file but with the site itself. Sucks, this map looked fun

I used dropbox so there shouldn't be anything. I uploaded it here now so it should be fixed.

5/5

Uploaded the map to the workshop!

Redunzl and I noticed that you had updated this map, so we replayed it. We didn't have any of the problems with the inconsistent flings this time. So we give this a 4, now.
