It's a shame this hasn't gotten more attention. It's quite neat and cozy.
It's quite simple but really creative. I especially like how easy to understand it was. The controls were intuitive and the goal was easy to understand. I think my main complaint gameplay-wise would be that the warmth meter and regular timer didn't really need to be separate. I feel like you could have gotten by with just the warmth meter.
Also one more thing which isn't exactly a comment on the game itself but rather a suggestion to get more attention in the future. You should export a web version next time too. I think many people don't bother downloading jam games and would rather play them in the browser.
I wish you good luck on the jam!
