this is a cool idea! if i understand correctly, i'm controlling the ground under the car, not the actual car itself. i like how the ground wavily oscillates. with some determination i got 2014 points, dunno if that's a good score or not haha.
it seems like there are points on the ground where the car gets kicked up in the air to make it harder? more feedback might be nice (e.g. a rock or something on the ground so you can see the reason for this kick-up instead of it feeling random). it might also give the game some risk/reward spiciness if there were more incentive to go fast instead of slow and steady which seems safer.
