I like the concept, and the pixel art is really cute! I think it's really hard to see snowballs though, and im not sure if im missing something, but I couldn't find the second snowball in the 3rd level.
It's there, just really hard to see because I didn't put a dark enough outline and since it's scaled so small it just get's eaten up from view. I hope to totally revamp the artstyle in the future.
