Nice challenging logical map with a sneaky hidden exit. Great work. Thanks!

Very nice, I liked this. It's easy to forget how one depends on the visibility of various "pointers" to complete a test e.g. the associations between triggers and their outcomes, such as the common "track lighting" (not sure what it's called) to indicate things like "this button will raise this platform". Doing it somewhat more blindly, like in this test, gives a different perspective.

Never mind, found it (5 seconds after I posted, of course ...)

I can get to the "high" area (as you described below) but after that I have no idea what comes next. The platform doesn't move, I can't find any switches, can't find any other portalable surfaces, went down the various pillars including to the bottom of various "pits" - just can't find what I need to do next!

I really does pay to look EVERYWHERE. Thanks!

@Diamond Knight: After you fling above the second portalable surface, look over the wall. That's where you need to go. ;)

Well, I must be a real dummy cuz I searched & searched & found not one thing to do... except fling & I couldn't figure out how that helped so I am totally lost.

Genius, sheer genius. Compact, precise, clever, and one of your deadlier chambers. There one pit that's wanting for goo, though. I got stuck once.

A little confusing at first, while you hunt around for the various elements. But it has flings. I like flings!
