What a good game!!
I loved the idea, that's something that every kid that dreamed about developing videogames experienced. The graphics are cohesive and the animations look really well. For just a short time of development, you really reached good visuals.
My only complain is the blind point of the car. It might be fixed with some transparency or with the shadow of the player through the car's structure. I think it's nothing to actually worry about. And, don't forget to add sounds.
Remember that movement in videogames is a way of expression, so, for future iterations try to give the player more options to interact with the environment and the level elements. A fun game starts with the characters' moves.
Excellent job!
