Sick! It matters that the start of each loop is the rightmost node it seems like, so it'd be nice if that was labeled somehow, but once i figured out that it won't accept a rotated solution it was pretty fun.
Yes! The start is at the right center of the nodes. I wanted to label it, but I had to start building since only 10 minutes remained until the jam deadline. (Could have done it in the extension, but that’s cheating haha)
