The writing sparkles with wit, and the game’s use of metaphor (that is, making it have literal consequences) called to mind Patanoir. Kotodama also gives a welcome depth to the world-building by giving a nod to familiar narratives such as racism or the role of immigrants. This seems to have some link to the title: according to the Oxford Dictionaries blog, which the game quotes, the concept of ‘kotodama’ applies especially to Japanese in its ‘purest’ form – that is, the language without any loan words – yet, definitions of what counted as ‘pure’ varied over the years.

Kotodama is relatively short, but is highly polished (I found the Poetry Dojo to be a stroke of genius) and very cleverly written. Highly recommended.
