Nicer solution than I did... I dropped out of the funnel, placing a portal underneath me, to get the boost up to the button. Yours is nicer! Thanks for posting.

A lot better lightning and it's even without that ninja part. Thumbs up!

Had me stumped for a while. Great logic!

As you say, it's not much of a difference. I just put a portal in the floor under the funnel to pull the cube down to me.

I know exactly what has to be done to solve Gigopler's test but I tried several times and just couldn't get it right. To those who can solve it I offer this line from the autogyro pilot (Bruce Spence) in the movie, The Road Warrior: "Reflexes! That's what you've got. Me, I've got brains."

Thanks @Miami_Mike
You actually stumbled upon an unintended solution. One of your steps should not have been possible. It is a very small step and not that important, but I had to fix it :)
Would you care to give it another try?

That was good! Here's my playthrough: https://youtu.be/21GPGsfDuV4

I still haven't solved Gigopler's version, but I'm not very good at those quick "ninja" moves and prefer tests that emphasize figuring out what to do rather than actually doing it.

I'll give Gigopler's test another try though, now that I have an idea of what I need to do.
