Scarf fidget maze

So I found this pattern around the beginning(?) of the year. It looks like The Ultimate Fidget--double knitting, wind a marble through the maze. I took a class through Stitches (RIP) to learn how to do double knitting, but this being different from side to side really screwed with me for awhile and I would take out more than I put in.

Now, I think I have it down, relatively speaking. I don't work on it that often--it's my work office lunch project--but I think I've got enough of it going (nearing the first page down...of many pages, mind you) to show you a bit. Here's a photo of the scarf with the pattern, if that helps any to figure out what is going on.

And here's more of it, on both sides now.
