I liked the graphics and sound design! The puzzles were fun too, the premise of the game also being pretty cute, set in a winter world. One issue I often ran into though, was the camera working against the platforming, where I would try to line up a jump, but the camera angle would occlude my character either horizontally or vertically. Freeing up the player character should fix this though if that's a route you'd want to take.
Fun game with neat platforming, nice job!
