Nice job. I love the word play in the title and the music is nice. The tongue is a neat mechanic that helps the game stand out from your average platformer. TBH I'm a little mixed on the timer. It's a neat concept on paper, and really helps tie the game to the winter theme. But with how far apart from the main character it is at times, it can be a bit much to keep track of both at times. I feel like the game could really benefit from some audio cue. Something like shivering or a chime that help you gauge how close you are to freezing, even if you aren't constantly looking at the timer could go a long way.
The other most major piece of feedback I have is that the character sprite feels a bit small on screen imo. It some adjusting to track such a small character on a big map, but if its any assurance I did make that adjustment fairly quickly.
Again, nice job with game. Best of luck with the jam.
