Bad map
1. Super-easy
2. Not polished (no clips when needed
3. Elevator

1) systematically when you start plying, you have to restart the map or to noclip out of the elevator because it doesn't start moving. I've seen that in a couple test chambers, I don't know if you can fix it
2) the offices have too much light, way too much.
3) if you try to keep your reflecting cube as long as possible, when you're about to go in a test chamber with a weighted cube it'll fizzle where the broken window is, which is weird since it's just a window, but pretty coherent since you don't want players to have that cube. Still, a little before that, players can actually use that reflecting cube to walk on the vac tube and access the void, so I suggest you put instead a real fizzler earlier in the path the player is supposed to take.
anyway, nice work, I can't do a test chamber like that.

Nice! Just one question, HOW do you start the elevator at the beginning of the level? I have to noclip out of it to get to where the level begins and I ate to resort to that.

Do you know that it's spelled suspension?

How to trap yourself:
1) Pick up Reflection Cube in Office
2) Walk to hole in wall
3) Throw the cube in as far as you can into the Chamberlock.

Fun easy map.

Are you aware you spelled "suspension" wrong? Or was that deliberate?
