[SP] Antimatter One
Many thanks!
I can load the map and I spawn inside the elevator but the elevator doesn't move and I can't get out... I suppose I'll have to go look up the noclip command to fly out of it.
It happens sometimes, it's not just my map. Just reload the map and it should work fine
reloaded it 3 times then gave up and no-clipped out. first map this has happened to me on and I've done pretty much all of them on here until now. oh well, either way was a pretty cool concept. I'm not sure if I did it right because I got to a point where I could shoot a funnel on a platform and ride it up so high I could see behind a wall and it looked glitched. Also there was some weird glitching when I rode the elevator down in the end, as though there was a leak in the level.
Either way, was fun and thanks for the it 
^No idea why it happens, it happens to me sometimes while playing other maps, usually if i alt tab the game as i spawn in the map. But no-one else or me seems to have the problem so *shrug*
Anyway i've updated the map a alittle, added a death lazer wall instead of a fizzler to prevent exploiting the funnel like the user above, general polish to the map and a few lines from glados
[/spoiler]I've had that black elevator thingy in my map too. No idea why it's happening >_> Restart usually solves it.
Otherwise a great map! The last puzzle was kind of trial and error and dying and stuff.. 
Wait, is that the reason why my noclip is slow-moving now so the parameters are cached?
I have this problem as well, ever since I played the map, my noclip has an acceleration to it, like I start off moving real slow and gather speed as I move.
It would be really cool if you could figure out a way to trigger the noclip without the noclipping part, a zero-grav room where you can fly around and shit. Cool concept. How to I fix my noclip though ? 
Get in touch with me on Steam if you need a playtester. The more people you have test your map the better, and if you check some of my posts you'll see that my playtest write-ups are very comprehensive.
Noticed a small bug in chamber two. If you portal down to the landing area for the AM the map will count you as in the toxic water for a short time while midportal. Could probably be solved by raising the surface a little. Just thought I'd let you know =)
Cheers!

Haha i guess i underestimate the reach of the gravity gun effect, the glass wall will be lengthed thanks.
As for no-clip, that was my bad after all, the elevator still had a left over trigger in it. Just go into your console and put your noclipaccelerate back upto 5 that should do the trick, since the trigger turned it down to 1 to simulate stasis
Thanks to the guys above for shouting out some bugs, will be fixed in the next update, along with a whooping great shortcut in the last room i completely missed 
How many chambers are there in total? Cause when I finish the third one the elevator gets stuck afterwards even though I stay in game. I reckon it's supposed to end there?
Also, in chamber 2, am I supposed to be able to reach the portal surface on the side of the starting platform by inching towards the edge until I can see it? Or am I supposed to shoot it from somewhere else?
