I hate rating things lol... I think what you have is VERY solid... it plays smooth and has a nice feel to it. 
The sounds go well with the environment and I'd love to play a more detailed version because it felt good... donno the physics I think... 
For what you have here, I think its very very solid! 

I only have a mac so unfortunately I can't play, rate or comment your game. Good job getting something up here though!

Nice music & sound effects!

A good little endless runner.

If you wanted to expand on it, the next thing I think would be cool is to start increasing the difficulty or different jump patterns or something. Maybe  introducing a second set of platforms above the lower ones that are harder to maneuver but offer more circles for faster points. Or increasing the speed of the level scroll. Maybe some circles cause you to lose and you actually have to avoid those.

Good stuff!
