RPG time again. This time it's more conventional in principle, I guess. Trail / RPG, rather.
If you know the track, you can do it in less than 10 minutes and it'll be some nerve-wrecking fun, hehe.
It has a decent variety of challenges, I believe. Everything from balancing to highspeed-coordination, jumps, climbing, exploring, finding secret spots that nobody would go to, because it's way too much work for some insignificant surprise, yes, it has it all.
...uhm...yeah, that smiley does it.
Have fun, give it a try... maybe that's the wrong order,uhm... give a try & HF!
PS: If you want a spoiler, I've uploaded a replay. It's not perfect, but it shows all the stunts...
