Good and fun.

Very fun test!

looks like i did it the same way as bullfrog. no problem here either

Great puzzle; I really enjoyed that - big thumbs up. I don’t know why people are having problems with the ball, it seemed pretty easy and reliable to execute the move, but perhaps I was doing by an unintended method – spoiler walkthrough video of, possibly, intended solution: intended solution? ? :D

Decent test. I would have an excursion funnel beam downward to the x and square button. It would make things quite a bit easier to execute. Also since you exported from the in-game editor to Hammer, I would think you would remove the symbols and move the antlines manually since the in-game editor keeps it automatic. Also it seems like there was no real benefit to exporting? Just an experiment?

Some time passed since I've done the test but I think if you switch the cube role with the ball it will make things easier.

Damn that ball was hard... There are two ways to get it where it needs to go, though, and I found that using the funnel rather than the rolling it along the bridge was slightly easier.

Not sure if I did the last part the intended way. Standing on the light bridge coming through the laser field, it's possible to jump to the chamber where the bridge is generated (with the cube placed on the fizzler button inside). If that's relevant, I did it the right way.

I know ball is awful but I need something instead second cube :P
in future may I will think about cubes which work only in one kind button :)

Pretty nice! I hate that ball lol
