It's probably best if you move on

Hmm, do I "have patience and a good reaction time"? Well, my "patience" is pretty good, I think, but my "reaction time" is pretty rubbish, as you know. Perhaps it's best if I just move on, unless you think otherwise?

It's pretty empty for a museum, there's no piece of art ! Except for the puzzle, it was pretty good

No - sorry too troublesome for me - even with the walkthrough below.

@nerdlingnation the portal angle at 1:12 is unintended which led you to skip a part and do the unintended fling at 1:30. But everything else is fine. Thanks, I was able to update the map.

definitely needed that walkthru , thanks nerdlington. not my strong suit

Here is a video of what I did: https://youtu.be/7vcgQ2F-Sn4
I think that what I did at about 1:30 was unintended. It didn't feel too out of place based on your good reaction time remark in the description, and I know that some of your other maps have included some tighter portal shot angles. I assume that the intended way used some other way to give the cube momentum at first which involved the 2 unused surfaces in my video. Anyway, it should be an easy fix if you want to patch that one out. Good map.

@nerdlingnation I give up, how did you get the cube redirecting the laser to the light bridge catcher for the first time? The only thing I can think of is you either threw a cube upwards or you jumped off the cube, grabbed it, then raised it above your head to drop it.

Solved this one a bit ago but didn't leave a comment. Very cool puzzle. I have a hard time with momentum sometimes. At least, building puzzles that use momentum. I didn't use the laserfielded surface on the ceiling; not sure what that's for. My solution felt completely logical, though.
