Great vibes with this one, well done!
I wasn't sure what the objective was.. I initially thought that you never end up delivering that one singular box and it made me chuckle, but looks like there is actually an end? Car controls were a bit tough to get used to and I would recommend restraining the camera movement more because the wobble made me a bit motion sick.
If it was a game about endlessly delivering a box, then it'd play great on subverting the expectation and you could make the driving itself the core gameplay experience.
Great submission!
