Controls are a lot of fun, sometimes get slipper at high speeds, but that may be intentional. Make shockwave more apparent, perhaps make boost a bit more noticeable. I think the flight ability is particularly awesome, and you may want to design a course that incorporates it more often, or perhaps makes it easier to utilize given what you've said about some peoples' difficulties with it. Can't think of much else to say, perhaps more obstacles or power ups if you wanted to add anything more? Overall I think it's a lot of fun as is though.
