The simplistic art style works for this. Some sound effects would have been nice.
Gameplay-wise, some of the collision shapes feel a bit off - I would bump into a rock when I was sure I was far enough away to clear it.
It feels a bit strange to have the snow cleared on a grid, but not have the player confined to the same grid.
Also, some feedback when you clear a driveway - a score change or sound effect maybe - would go a long way.
Good entry - gameplay just needs a bit of polish.
