@war_gerbil: This chamber has been updated to adjust the trouble elements to better explain or make them not the challenge you encountered (as this "was not part of the test"). If you would not mind re-playing and giving further feedback that would be appreciated. Thanks all the same!

@DDR Khat: The first chamber on the left side has kind of a "basketball shot" with the round cube (my first time to see this one) that shatters if you miss your throw. That one took several tries, but I eventually got it. I cleared all the puzzles on the left side of the main hall. On the right side of the main room, however, first chamber (marked by the square), it seems to me that you need to put a portal both on top of the ramp and on the floor below that, and jump from the top to the bottom to get the speed to look over the raised section. I wasn't able to get the jump high enough to generate the speed necessary to see anything portalable. That's where I gave up. Hope this helps, because it looks like an interesting set of puzzles otherwise.

@war_gerbil where did you feel this precise jumping was? I hadn't intended for that to be part of the "challenge" this map presents?

This seems to require a bunch of very precise jumping. Personally, I'm only going to try the same jump two or three times before it gets to be a bore, rather than a puzzle. Sorry.
