Play Granduel - Shinki Dungeon no Hihou (Japan) Online
You crawl dungeons, fight turn-based battles with weird little monsters, and poke at walls hoping they’ll open—classic GBC RPG vibes with a side of "wait, what does this kanji mean?"

Game Overview
Granduel - Shinki Dungeon no Hihou is one of those Game Boy Color RPGs that slipped under the radar—probably because it never left Japan. At first glance, it looks like your standard dungeon crawler, but there’s something oddly satisfying about the way it handles. The turn-based battles are snappy, and the dungeons have just enough twists to keep you poking around corners for hidden passages.
The pixel art pops in that classic GBC way—vivid blues and greens everywhere—and the monsters have this weirdly charming, slightly janky look to them. It’s got that old-school Dragon Quest vibe, but with a dash of mystery dungeon randomness. Sure, the menus are all in Japanese, but if you’ve played enough RPGs, you’ll figure it out (or just keep mashing A until something works).
Honestly, it’s the kind of game you boot up thinking you’ll play for 10 minutes, and suddenly it’s been an hour because you need to see what’s on the next floor. If you’ve got a soft spot for forgotten retro gems, this one’s a solid deep cut.
