Gussun Oyoyo

Gussun Oyoyo is a puzzle game developed by Irem for the Arcades in 1993. In the following three years, it saw several ports (and a sequel) for consoles. These ports were handled by different developers, and are subtly different interpretations of Irem's source. Irem themselves would eventually produce a PS1 sequel in 1996: Gussun Paradise, known in Europe as Yoyo's Puzzle Park.
