Nice to see this map back, and it works well for ring racers. The sneaker-panel u-turns especially feel good, with ring racer's sliptiding.
My only real nitpick is it feels like almost all the rings are fairly out of the way - at the top of those steep ramps. I think it'd feel better if there were some rings sprinkled a bit closer to the racing line.
Hopefully you'll be able to address the bot difficulty in the future, once we get some mapping guides :P
