I actually love the slippery movement and the fact that you can't jump while moving. Really adds to the feel of skiing. Plus the jumping adds to the challenge a little bit since platforming is the main challenge. The art is really awesome too, I love your signature style. I think it would be cool to add a camera pan up and down when the player presses up or down to animate looking in that direction. I think some more levels or being able to talk to the characters would add a lot to the lore and story as well. Overall, I love it!
