I loved the snowball mechanic you made to get larger/smaller, and how well your levels made use of that. It was so satisfying to throw the little snowballs, I think partly because of your sound effects. The controls felt really good, too. Unfortunately I got stuck in the second level I believe, couldn't seem to jump high enough to get anywhere else. Looking at others' comments I guess I missed a wall jump ability. Adding some signposting to let players know that exists would defs be helpful. I think there's lots of potential to update this one - you've got a really solid look and feel here already. Nice work!
