Good one. latest changes look good, however it is possible (it was possible before, I forgot to mention it) to bypass the fling to get to the pedestal button that releases the cubical cube by landing on the angled panel from above and portaling over to where the button is.

Not sure how you intended the tester to exit the lazer-grid section after "catching" the round cube, but I found a patch of blue goo that worked for me...
