Otocky was created by Toshio Iwai (http://en.wikipedia.org/wiki/Toshio_Iwai) in 1987 and was only released in Japan for the Famicom Disk System. It is best described as a musical side-scrolling shoot 'em up where the primary weapon is a ball which, when fired in one of eight directions, plays different musical notes on the primary instrument quantized to the beat of the background music.
