Very nice aesthetics, I loved the big moon in the background! It plays very smoothly with a gamepad (although every restart I had to use the mouse to click the new journey button.) I made it to 314.something after a lot of tries, then couldn't get past 200 for a while, then I made it all the way to... 314.something again! So I think that's as far as my mountain biking can take me at this time.
I saw your youtube video of the full route, I don't think I'd be able to see the ending otherwise. :)
