Interesting. Willing to try. How did you imagine "combat", dealing damage and recovering HP? Would HP be used for all kinds of conflicts, not just combat? Do enemies deal 1 HP damage per "Attack" and vice-versa?
ohh, good questions!! normally i imagine an enemy would deal 1-5 damage depending on how dangerous it is, and likely have approximately double that in hp. i also imagine you'd regain all lost hp over a long rest, but my roots are in d&d so that's where my mind runs first. it could be fun to use hp for more than just combat health, or include a separate track (dogs in the vineyard and cypher come to mind as examples). you could also run combat more narratively, asking questions of the percentile dice to see how a fight turns out overall. you should definitely do what sounds best and most fun for you!
