Strong atmosphere, but I can't help to hold it against the game that it is just a short timer until death with seemingly no way to impact it on my end. While I get that there is a message in this, it felt too depressing with no agency.
That being said, if depressive is the mood you want to go for, you did really well with the dialog, the visual design and the post processing. Personally it would have made sense to me if the campfire would have been dying down over time, too, but that's a bit nitpicky, I'll admit.
