What is the author's style in Lost in the Funhouse by John Barth?

The story is written from several points of view, including first-person, third-person and omniscient. The first piece written about Ambrose is written in a first-person narrative and told as a reflection on the past. When Ambrose appears in later chapters, however, the narrator is separate from the character and is telling the story as if looking in on the boy. Twice the point of view is given from a non-human form, as in the sperm in “Night-Sea Journey” and the tape recording in “Autobiography,” and other times it is apparent John Barth is speaking directly to the audience.
