I spent way too long trying to figure out why the guy and the ice cream shop were flying, and how he would move horizontally in he air…
I couldn’t tell what I was looking at until I searched for an explanation. All I could see was a person falling into some water past a floating ice cream stall. It’s supposed to be a beach:

Path that maximises time would be some kind of space-filling curve. Maybe it does that off panel?
It’s to do with light paths and diffraction. The time maximising path still hast to be a valid path.
