Beautiful setting, fantastic illustrations, but generally underwhelming as both a story and a set of mechanical interactions. Making explicit the implied meaning of the illustration you show the client is a bad move, both because it's hard to connect the ambiguous and sometimes arbitrary glyph with the definite answer and because letting the client interpret is a more interesting way to express their character. Either way, it feels like a tutorial but without the part where you feel like you've gotten an understanding of the mechanics by the end.
