Unfortunately it didn't work for me with my trackball mouse. I tried multiple times. This is very likely also problematic for accessibility without another verification pathway, as assistive devices and screen readers would fail the heuristics too.
Interesting idea but it didn't accept me the first 3-4 times I tried to draw the path on laptop trackpad - going slow led to it failing before I was finished, going fast led to messy paths that were rejected as well. Could something like this work for users with different levels of dexterity?
I am on a mobile device and I consistently find that my finger is not precise enough to draw a path; it kept complaining about path “not quite right” where my path just touched the wall a little bit. And when my finger literally obscures the screen while drawing, it essentially means I have to memorize an entire path before beginning.
This requires significant spatial thinking skills and short-term memory for a human and it is absolutely unfair for a human to expend that much cognitive power to access a website.
The description doesn't make sense either... like "Color-word interference at maze decision points", but there are no colors (or words) at the decision points.

I worry a bit about accessibility but that is a problem all CAPTCHAs have
