I enjoyed it a lot! There could be music and more sounds when racing. I liked the puzzle-like mechanic of fitting the car parts together to optimize space and pack in more. There is just one issue: when a race is about to start—specifically during the "buying" phase—you are charged the moment you pick up a part, and some can only be resold for a lower price. In my opinion, it would be better if the charge applied only when you placed the part "inside the vehicle," with a refund issued if you removed it before the race began.
