That challenge was surprisingly hard. Even with the couple of landmarks (I think a few small bushes). It’s weird how high the difference was between what looked like a perfect circle and what was actually expected. It was almost like an optical illusion.

I got 100% (the second moon) purely by the feel of the controller. I didn’t even look. I just started an arc and held fast. It’s amazingly difficult to walk a perfect circle.
