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.
Oh, I'd also be curious to hear what your thought process was with deciding that the B button would progress dialogue boxes instead of A for controller. It's not a big issue in the grand scheme of things just different enough from what I'm used to, to perk my curiosity.
Again, nice job with game. Best of luck with the jam.
