Ashenheart is a mystical science fantasy post apocalypse TTRPG. It's got a lot going on, but honestly this works in its favor.
Ashenheart's PDF is 24 pages---with a layout that I did, and so I don't feel comfortable commenting on whether it's good. Use the screenshots for reference, and decide how you feel based on those.
Setting-wise, Ashenheart is weird and vibrant. The tech level is the 1940s, but there's gods and ruined ancient cities and hell is an ocean that occasionally springs a leak into reality and people domesticate giant sea slugs. It's rad and worth your attention.
Mechanically, Ashenheart is pretty simple, but it has a few interesting twists. Default rolls are a single d10 on a chart, and lower numbers mean damage (Stress) whereas higher numbers heal you.
If you take enough Stress, you can gain Virtues or Neuroses, which let you modify future rolls. Similarly, by being exposed to the game world you can also take Mutations, which do the same.
The overall feeling is sort of a nautical divinepunk Fallout New Vegas, and I hope you'll check it out based on that alone.
