Fun little game! The only real issue with the game is that it's difficult to tell when you're in the air, so you'll be holding left or right and just crash into the ground as you suddenly lift into the air. If this is fixed, it'll be a great little skiing game.
I'd love to see the mountain expanded in all directions a bit so it's in the center of the map rather than the top of the map. Adding a route that's from the summit to the bottom would also be fantastic!
