Nice! Looks really good and you can totally see how it relates to the theme. I did have to download it though, in the browser it was basically unplayable. I suspect removing the snow particles on the web version would help a lot. In my experience a lot of people will only play the online version because of the risk with downloading, so maybe keep that in mind for future jams. If you keep working on this a couple of suggestions I'd make are adding a jump button to cut corners (I kept pressing space and resetting :D ) and smooth the transition to first person on level 3. The sudden jump is a bit jarring at the moment.
