I actually loved that the tractors were not out to kill you on purpose. That makes it for a non-violent game that with time still gets harder (slowly though).
I didn't quite understand the pumpkins, though. Were they just for the extra audio effect?
Interesting, I did not think about it as a non-violent game. I like your idea of thinking outside the box.
I think the pumpkins gives you an increase of speed for a short period of time,
