I've now read it. In terms of system, though D&D derived and with clear Black Hack inspiration, it's very much its own thing. Post-OSR, not afraid to change things rather than keep them as legacies, consistent and with a new magic system, with spells that suit the setting.
The setting is incredibly charming. It's Arthurian by way of high fantasy, inspired by mythology with no pretense of history. I want to run it- it gives me warm feelings and plenty of ideas.
