Oh yeah; a couple of further thoughts. After I was unexpectedly revived with half health and ran away from the wolves I tried doing First Aid on myself. First attempt failed and I lost 3HP. I had not been told I was bleeding out or anything, so I suspect that if I hadn't tried the First Aid I would not have lost those hit points. Second attempt succeeded but I didn't get any HP back -- so was there any change in my status? I said I was going to rest, so the system said I sat down but I did not sleep or heal; I had to get pretty specific about doing a Long Rest and then I slept and healed. It's a little tricky knowing how to specify what RPG-mechanic thing you want to do, since there's no menu of specific actions to choose.
Also I haven't gotten very far in this yet but the only thing I've gotten XP for is fighting unsuccessfully with the wolves. Maybe GURPS doesn't do things this way (it's a long time since I read the GURPS system, and I never played it) but I like it when slaughtering things isn't the only way to get experience. Exploring, finding places and things, practicing skills, even some conversations could all give XP. Although it's obviously tricky figuring out how to balance that right.
I can imagine that all of this might be tough to get an LLM to cooperate on.
