I kinda like that bug where you can keep driving when the fuel is empty but the camera stops moving. The fortune cookie says: "Even if you lose sight of your goals you might find new motivation (fuel) if you keep moving on"
I really like the aesthetics and the slow pace. I think just adding enemies would have made it kind of generic - maybe you can find another way to make it more engaging then just "stuff that smashes your face in".
Good job!
