Play Dragon Slayer I (Japan) Online

Game Overview

Dragon Slayer I on Game Boy is one of those old-school dungeon crawlers that feels like it was made for late-night bus rides. You start off with basically nothing—just a sword and the vague instruction to go kill a dragon—but there’s something weirdly satisfying about slowly piecing together how everything works. The dungeons are mazes in the best (and sometimes most frustrating) way, where you’ll backtrack just to remember where that one door led.

Combat’s simple at first glance, but enemies hit hard if you rush in. I learned that the hard way after getting wrecked by a bat in the second room. The pixel art’s got that chunky Game Boy charm, and the music sticks in your head way longer than it should for something this retro. It’s not flashy, but if you’ve ever wanted a portable version of that "one more floor" dungeon grind, this nails it.

Fair warning: it’s from that era where games didn’t hold your hand, so expect to scribble some maps on scrap paper. But that’s part of the fun—or the pain, depending on how lost you get.
