Moving through the levels felt great, especially on the 3rd and 4th levels! I appreciate the tutorial too, I was able to feel how each move was useful. The sensitivity threw me off a bit at the beginning - it worked great for the fast sections, but for the slower parts, it was pretty slow (I wonder how it would feel to have it adjust dynamically based on speed?). The speedometer was a great addition too, it let me more easily tell which of my moves was making me go faster. Great stuff!
