Finally taking a *real* look at this since I got in the racial justice and equality bundle 3 years ago, and I like it a lot. I'm not the biggest fan of the hyper simple flat chance combat, but I have my own homebrew, more nuanced combat system I can slot in. Very good Bloodborne-y goodness at base. I like that there's explicit room for homebrew. Very good job. When I can figure out the itch mobile app UI, I'll rate it.
Tbf my combat system is also a single d6 roll, just a low-high nuanced one with diagetic wounds. Roll low and you do badly, and will likely get hurt. Roll high and you do good, and hurt the other guy. Just track the wounds till it feels like the npc or pc should be dead. Only a step up in complexity.
