Can a 12 year old play Firewatch?

Can a 12-year-old really play Firewatch? I'm curious to know if the game's content is appropriate for such a young audience. Firewatch involves mature themes like depression, loneliness, and even some references to drugs and alcohol. I'm wondering if these elements might be too intense for a child of that age. Do you think the game's rating and content are suitable for a 12-year-old, or should parents consider waiting until their child is older? I'd love to hear your thoughts on this.
