Feedback for my Game "Snow Hopper" ... Thread

This is a little Prototype for my Game "Snow Hopper" ...,

What do you think?

I like it, graphics are nice and simple. Had a LOT of trouble with the wall jump though. Gave up on level 3. While I did eventually make it up there, that was after a bunch of trial and error, and without the carrot, so decided to give up. The wall jump needs to be refined, like when I perform the wall jump, it takes a second to register that I'm pressing the opposite direction key, and I lose height trying to climb up a shaft waiting for the button response to make it to the other side. But if that got cleared up and wall jumping was easier, I feel like I'd probably play it through.
