That is really awesome!
For the first time, it actually felt (for me) like an actual "racing" game.
I did terrible at it, but it was really fun. A spiral came up so fast that I was already through it (and hitting grey blocks the entire time) before I could even react or know which way to go.
It has two things against it though.
1) - At 16 minutes, it's a bit too long.
2) - When the music finally arrives, it ruins the experience.
That's just my opinion, though.
I will be giving this another try sometime when my reflexes (and caffeine load) are at a higher level.

Thanks for posting this -- I do hope others give it a try!
