My biggest critique is that the game ends just as it is starting to get great. I was just starting to think about how interesting things could get when you introduced the ice sliding puzzle and then that was it. Don't take it too personally though. Making a game in this short of a time frame is tough, and I can definitely appreciate what you were able to deliver. It's got a nice art style, nice audio, some interesting gameplay mechanics, nice theming, and a neat transition. There's a lot to like about this one.
