@levitatingspleen glad you like it! For point 1: nice observation there. Something to look out for when making other funnel based puzzles.Will have to check out point 2 :)

Nice and solid chamber on your hands here. I like how you've used the available space in the chamber, and how you end up traversing all the disparate corners of it throughout the different stages of the solution. The solution itself is fairly simple, but it's fun enough to execute where that's not a problem. Here's a couple of notes I made on my playthrough.

1. if you're fast enough you don't need to use the reverse polarity button for the funnel
2. If you want to make a more challenging version of the test, try extending the fizzler to cover the entire lightbridge gap, and add a floor mounted pressure button to deactivate it, I think the test is still possible? This isn't criticism of the chamber itself just and idea I had while playing it.

Hope this helps!
