>>> TRIVIA
----------
The title of this game translates from Japanese as 'Reverse Scale Bullet' and is an example of 'ateji' - fitting the kanji phonetics to the name of the game to give the name double (sometimes even triple) meaning.
The name of the twin characters, Orsa and Mayoru, is a play-on-words of the third largest constellation of our solar system, Orsa Major, which means Great Bear.
All stages in this game share the same music theme but remixed each time!
The game forbids the initials 'SEX' on the high score table. If you try, it gets changed to 'AAA'.
Pony Canyon / Scitron released a limited-edition soundtrack album for this game (Welcome to the Karu Land - PCCB-00196) on 17/11/1995.
