Overall it looks pretty good. Seeing the Dwarf's breathe was a nice touch, and the snowing effect was done well.
It's very linear, though. There is literally only one path that you can take and not a single platform to jump on that might lead to a more rare mineral deposit (I like the addition of mining, though).
As far as combat goes the regular attack should have a bit more "knockback" to it. That is, when you hit the enemy they should be pushed backwards. The super attack, on the other hand, does this quite well.
Thanks for the demo!
