Cool game, I like the art and the sound design, it helps convey sense of dread.
It was slightly frustrating at first because my instincts were to get as far from the avalanche as possible as fast as I can then to spend some time resting to get the cold meter down but after a few runs I realised that's the worst possible strategy due to how the avalanche works.
Once I realized how it works the game was actually fun, I like the idea of kinda riding the line of the avalanche dodging spikes.
Nice work.
