Nice track:

+ Globally, the colors and themes are well done.
+ Track is more or less constant. You didn't try to have every single element of the game in it.
+ Moderate difficulty, but still some challenge.

- Some colors... Just don't fit with the rest. Some object's colors are just in contrast with the road, and some colors transitions don't render well (Neon red VS neon green )
- The first time you encounter the very fast wheel saws, if you're going full speed, you can't predict them, and it's not by skill if you make it further, but by luck. Maybe slowing them down a little would be nice.

That's all for me.
