Nice to see a lot of SkiFree love, although I guess it might not be as nice for you since everyone will compare your game to the other SkiFree clone, and probably unfavorably (sorry!).
I do think the speed cap makes your game play better, though, and the density of obstacles is nice as long as you don't go diagonally like Ivchill pointed out. The art style also feels closer to the original. Had you included more objects and (most importantly) the snowman, I could easily see myself preferring this game over the other.
