Well done! I know how it feels when the development process takes many times longer than expected. On the bright side, the time shortens when you attend other jams or develop other projects. For the feedback, maybe you could consider continuous steering instead of manual steering from the player (this would also give you control of the tempo of the game by adjusting the speed over time), and having the camera at a fixed angle rather than following the car as it moves can make the game feel smoother. Besides that, the game is very fun to play, good job!
