The game itself is a very simple mechanism.
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.
It is important to take time to quiet your mind and forget the fatigue of daily life.
This game provides players with such time.
