This is a course that is quite hard to complete, I'd recommend using a steering wheel.
I love making these tracks, so I'll make more of them in the near future!
Good luck and be aware of the surprises this track will throw at you!
Nice map! I am giving 4 stars because it has way too much time spent inside the tunnels. I think if you convert some of the tunnel run to open air (making it a nice balance between the two), this would be a solid map! Nice work!
