What is the author's style in Riddley Walker by Russell Hoban?

Riddley Walker is narrated by Riddley, who writes in an invented form of English, ideated as a futuristic version of a Kentish dialect. The language is a central element of the novel and language itself relates to the novel’s themes of interpretation, history and mythology. While initially difficult to read and understand, the reader acclimates to the almost foreign language, especially when reading the work aloud, as the words are written semi-phonetically.
