Forgetting the busyness and coldness of daily life, we sometimes gaze at the flames and then at ourselves. It would be nice to have such a time.
During the day, you gather resources, and at night, you connect your life with the flame. If the flame goes out at night or if the fire is not lit by night, that's the end of the game.
You can use the points you earn to upgrade your equipment to make it more survivable, and then try again. You can try to see how many days you can survive. Or just stare into the flames.
