The music is great, but it stops after a few minutes - would be awesome if it looped continuously.
I know it's still in beta, but the wooden obstacles could use a box collider (though I’m guessing that’s already on your to-do list).
It might also be fun to gradually increase the speed over time and add more randomly generated wood obstacles to keep the challenge fresh (again, probably something you’ve already planned). I’d also suggest syncing the music speed with the running speed - it could add a really cool dynamic feel to the gameplay.
Finally, I’d love to see jump and sit-down mechanics, with specific obstacles that require crouching to get past. That would really add more variety to the gameplay.
Also, great job on the infinite road generation!
