Looks pretty good, although your tree textures could use a beauty pass. Though the tendency to oversteer in corners is a bit much. Perhaps make steering angle change increase exponentially the longer the left or right key is held down? Would add an element of skill! Anyway, nice game.
How hard could it be? Hard enough to make me give up at 129 seconds! haha! Bravo sir for turning such an simple and elegant concept into such a distraction. Love it!
There is no bounding box to the playfield. Fell through and could not figure out how to get back up! also, no game over/replay condition. Other than that its an interesting concept, keep it up!
