I don't know that this is the sort of information anyone is interested in reading, but I just wanted to wax poetic about the genre. 

When I was a child, my favorite genre of books was very specific: the "a single child survives with no contact with civilization and builds a life on their own" genre. I can think of four books off the top of my head: The Island of the Blue Dolphins, The Hatchet, My Side of the Mountain, and The Cay. I also remember reading The Swiss Family Robinson in elementary school, and it has the same sort of energy, if not the same specifics. 

Fast forward. I am a Punisher fanatic. What a lot of people overlook about Punisher appreciation is that it isn't necessarily about watching him shoot bad guys, it's about a single person, alone, with the bad guys and the good guys all against him, prevailing against impossible odds through sheer (bleeping) will. My very favorite of his comics is a three issue arc from the original '70s run where he is dropped, alone, injured, unprepared, and unarmed in the snowy woods and ends up fighting a bear. Nothing about punishing, nothing about criminals, just survival. 

Fast forward. I start playing video games. I use mods to amp up the immersive grittiness of RPGs, and once accidentally turned Skyrim into a survival horror game. I really enjoy playing Ark: Survival Evolved, but only for the first 70 levels or so, and always alone. I discover Subnautica and the only thing wrong with it is that it's too short. Astroneer (to a small but oddly enjoyable degree), Stranded Deep, Grounded, Green Hell - the genre is rife, but of course I need more. Actually, I find that too many of them make survival too easy, too soon, and remove too much of the grit.

A keen-eyed observer might notice that what all of these are lacking is tutorial. I'm not a survivalist myself; I couldn't do it. I don't hunt or study bushcraft or watch instructional shows that would teach me how to make it. You know what I do watch? Dude, You're Screwed! and The Wheel (2017). All of these have a veneer of gritty instructionalism, but what they're really about isn't a guide to surviving... They're the story of watching a single person with no resources dig in and overcome (or, occasionally, not).

All of that is what got poured into Hopeless: Just Keep Breathing. What started as a by-the-numbers "hey, I bet I could make something with this SRD for that game jam" turned into a love letter to the grit and determination of the sole survivor in a hostile environment, my excuse for writing survivalist fanfiction while disclaiming responsibility for their hardships and impressiveness. It's fine-tuned to what I look for in the genre, of course - journaling with the state of mind, Hope, and message prompts and mechanics to really be able to dig into the survivor's mental state and see what they're going through in the situation, so you can appreciate just how impressive they are by appreciating just how hard it is. Injuries and Constitution checks to make them suffer, and to make them more impressive for what they do while suffering so. A fairly adaptable crafting system so they can use their environment to survive. Resource management mechanics and chance rolls to make it actually feel like they have to work for survival and they're always a couple bad days from disaster. But character death being a narrative choice instead of a baked-in consequence, and the Willpower mechanic to make it a little harder to lose Hope, optionally make them more impressive by holding out longer. 

The Breathless system should take a lot of the credit, of course; the shrinking die size core mechanic is really excellent for the desperate feel of a survival situation, the whole crafting system is based on the original items, and the narrative abstraction, while something I wouldn't love to play with with other people, is very suitable for a solo writing game, I feel; it gives you the freedom to describe how the survivor pulls off the whole scene instead of being stuck on "does the knife hit?" I'm really glad I found it. 

If you read this far, thank you for indulging me. You're a rock star; I can tell by your cool taste in reading materials. And if you're interested in Hope(less): Just Keep Breathing, thank you so much.
