I'll do an in-depth review once I have the time. Besides Touhou, TTRPGs are my main hobby, and this game has been on my mind for a while.
The short version is that this game is a mess, and might not even be technically playable as written (or, perhaps, as translated). Every other Touhou TTRPG I've seen has been straightforwardly bad, but this one isn't just bad: it's baffling.
