Magical Saurus / Zaurus (マジカルザウルス) is a cancelled level-based action / puzzle game that was planned by Natsume (?) around 1989 – 1990. Players would take the role of a boy that had to survive to maze-like levels, avoiding enemies, moving boxes and pulling levers. Not much more is known about Magical Saurus or why it was never released, but it seems it was mistakenly listed in the Japanese Game Boy Encyclopedia as a published game. Some more screenshots were published in japanese magazines such as Game Boy Magazine Vol.5.
