Hyouryuu Shounen Keith (Castaway Boy Keith) is a cancelled action RPG that was in development in 1990 by Epic / Sony for the original GameBoy. The project looked a lot like Zelda: Link’s Awakening, but Keith was in the works 3 years before Nintendo’s title. The game’s plot was also similar to Link’s Awakening, as Keith sank on a small island called Harrods Is, where he had to complete dungeons and find musical notes to defeat the final boss.
In november 2009 Chris Covell was able to scan an article about Keith from an old Famitsu magazine and you can find more info and images at his website.
