At first I wasn't exactly sure what to do, but then I had a very nice experience. I really like how the beast/monster didn't have an exact form but was blocking the snow. That being said (it might just be because it is not a type of game I usually play), I would increase the number of snow particles to make the monster a bit more visible. Oh and the game doesn't exactly scale properly on 16:10 screens. If you would want a fix then just increase the height of the white rectangle acting as a ground (as I was able to see below it on my laptop when in full screen)
