Satisfying
It was pretty okay. I'd like to see more, as in: different people to run over, moving at different speeds; some levels, where it gets harder and obstacles (like lampposts or trees or parked cars) increase; and different backgrounds (for the different levels). It wouldn't be hard, considering how you've already got the movement and collision functions up and running.
The music was great, though, and the gradual increase of blood on the hood was a nice touch. Could you do that on the back, too? I like backing over them!
