As I said before, "bipolar" doesn't work because you're using it as a pun on "Insane". But you're using a different definition. Insane is supposed to imply the map is "Insanely difficulty" not that it "has a mental illness".
Imagine a spread like this: Amicable > Conforming > Impenetrable > Schizophrenic > Supernumary.
Amicable is a pun on "Easy" as in an "Easy-going / friendly person"
Conforming is a pun on "Normal" as in a "Normal person".
Impenetrable is a pun on "Hard" as in "Very difficult to break through"
Schizophrenic is a pun on "Insane" as in "psychotic, having a mental ailment".
Supernumary is a pun on "Extra" as in "extraneous, additional".
Clearly, this won't work.
