Wow… this is indeed quite the update.
I’ve watched on with utter interest as this game has developed (I’ve ran 10 sessions of v05 now) and it’s been a joy to see it come alive with each and every update. Without a shadow of doubt I can say this is a top tier hack, a GM has everything they need to get a game moving. The setting and theme are pouring out of the pages.
Ikezu-ishi can comfortably take its place next to the greats such as Liminal Horror, Monolith, We Deal in Lead etc.
Well done!
