visually very nice, the character got a nice getup. a bit more variety in jumps would be nice, maybe moving to the left every once in a while. I'd also like if instead of a hat and human button there was just one to toggle between and it'd be nice if I was able to use my right hand to access it. q/e for shape shifting and a/d for movement feels like a lot for my left hand. as a one handing game W and or S would be nice for shapeshifting, you also could move jumping to W and use space for shapshifting. if two hands are vibes then enter or a combination of arrowkeys for shapeshfting would be enjoyable. I ramble.
Anyways, you did well. you got control explanation in the game, a nice looking menu, and your snow particles look great.
