One of the best so far! Super cute game, the art is awesome, the gameplay is fun, but I completetly agree on DrJedd on the change of direction drifting. I liked that you looped thorugh the level if you kept on going straight, I'm not sure I would have thought of that :p
Towards the end the crows were really annoying, maybe if we had a way to deal with them, even temporarily, would have been cool. I forgot if they are also in the movie and if Kiki does something to get rid of them though, it's been a while since I've watched it!
