It's very pretty! I love the look of the trees, the overall visual style and everything. I really like the idea of the story too, it was nice to slowly learn more of what was going on and the ending was very emotional!
In general it's somewhat slow - you could certainly speed up the text scroll a lot for my taste. I also found it a bit hard to figure out how the wind worked, in a couple instances I got separated from my ice block and then just sort of had to muscle through - it would be nice if it could somehow be a little clearer that the block was blocking the wind, or which areas were walkable or not.
