In this test chamber you have to solve 4 puzzles to activate a tractor beam which brings you to the exit.
The 4 puzzles have different difficulty Levels. When you are in the test it wont be difficult to orientate, there are 4 fizzlers which lead to one puzzle each.

Gel-puzzle: medium-hard
Lazer-puzzle: medium-hard
lightbridge-puzzle: medium
cube-puzzle: easy

Thanks and have fun!

Not bad - I like the hub structure and enjoyed the puzzles in general, though I kind of blasted through them pretty easily.... The laser puzzle has a bit of an exploit - see here (.dem file):

The gel puzzle was probably my favourite of the four, though the ending was a bit flat as you basically just had to repeat what you did first time round. Still, had fun, thanks for uploading!

Thanks for the feedback! I agree with you last point. How can I read dem files? :S

EDIT: I Looked it up in Google.
EDIT2: LULZ! Thanks for the glitch!
