Game Boy World #057: Ayakashi no Shiro [Seta, 1990]

Game Boy gets its first old-school dungeon crawler, one of the least common genres on the system. This one offers an atypical setting for the genre (ancient Japan!), which is aesthetically cool yet somewhat frustrating in practical terms: The game text, which has never been localized or fan-translated into English, displays entirely in cumbersome traditional hiragana script (even English loanwords like "damage"). So it's a bit tough to play if you're not comfortable with reading awkwardly displayed Japanese text—and the heavy need for grinding up experience points doesn't help. It's not a bad RPG, though! Just a bit unfriendly to foreigners.
