I started this chart a couple years ago and abandoned it. I started making it because there was a debate about whether or not overcharting was always bad (if you don't like overcharting, you probably won't like this chart!). I didn't finish the chart and went back couple times since to see if I could make it better, but I ended up not having any inspiration to improve it much. It's fun to play, a little repetitive, but it feels like it's missing something—and I could never quite think of what to do for the ending.
The original idea was to have it only flow counter-clockwise without it feeling repetitive. I think it's mostly still flowing counter-clockwise, but after coming back to it again after a year I didn't really try to force it anymore.
Might make an extreme chart that's not overcharted.
