Nice game, had fun playing it. But please make the camera rotation smooth! I died quite often in the beginning, so maybe add health for the player so he can take a few hits.
The minigames were a bit annoying, I just wanted to drive and don't hit cars, that was enough of a challenge for me. I would suggest to either place them every time you delivered something or get rid of them totally and focus more on the driving itself. You could for example add power ups or coins you can pick up while driving or place ramps in the world you can use for a jump. If you want to keep the minigames make sure you communicate clearly what is happening, sometimes I couldn't tell right away if I got it right and what would happen if I didn't.
Overall you made a nice game!
