Fun Facts regarding "Cirno's Perfect Math Class":

* This song is so ridiculous and hard that it is more commonly known in some
  circles by its abbreviation, "CPMC," one of two songs in my pack that I
  often refer to by its abbreviation (the other is "Captain Murasa's Ketsu
  Anchor," which is "CMKA").

* I don't care what anyone says.  Perhaps she *is* a bit lacking in the brains
  department, but things have changed from the olden days: No longer can anyone
  make fun of Cirno for being weak: "Great Fairy Wars" has proven that Cirno
  is indeed strong.

* And so must you be to clear this simfile; Expert is a 12 requiring some fast
  footwork and some hold-and-alternate ability.

* On all harder difficulties (particularly noticable on Expert), you drop
  everything else you're doing during the chorus to follow every time
  Cirno herself says "baka, baka."

* Hard and Expert both sport a handplant at the very end of the song (an up
  arrow, right above Cirno's head where Iku pops the balloon in the video if
  you're playing on the left side).

* The edit is a lot of fun if you like the song, but can't pass Expert and
  want something a bit more difficult than the Hard chart.

* The long version of this song is in my "Pure Love Power" soundtrack.
