Well, the story was nice and it have a good artstyle. I give you credit in what you made but there a couple of things that I would point out.
The animation was too slow, almost every movemente where at the same speed, and that could make some lose of impact, some actions like when he hit the boar and the faeris hit the snake should be faster to give it more impact.
I like the story (or at least the idea of it) but I think that it could turn out better if you don't tell that it's a game until the end, that could leave some sense of surprise.
beside of that, I think that it work pretty well, nice job.
