Interesting concept! Reminds me a bit of Tiny Wings, which I love. The speed boost from candy canes could maybe be exponential instead of linear. In the beginning getting 2 MPH more feels nice, but later, when I already have 30 MPH, getting 2 more isn't as big of a deal. So maybe the boosts being larger later on would help give the player a feeling of progression?
Also, I got stuck at one point in the map where my cane would just fly up against the wall in front of me, and I couldn't gain speed forwards, which was unfortunate. But all in all a nice game!
