Very cool concept of combining a strategic card game with racing! At first, I had a bit of trouble understanding what I was supposed to do, so maybe an introductory tutorial or short manual in the title screen could be helpful. I also wasn't sure what collecting candy canes does.
As it's a racing game, it would have been cool to have a "faster" tempo somehow to really feel like I'm racing. Not sure how to implement that, though. Maybe visual effects or time limits? Or maybe the racers move all the time instead of the game being turn based?
