Play Oni IV : Kishin no Ketsuzoku Online

Oni IV: Kishin no Ketsuzoku is one of those Game Boy games that makes you wonder how they fit so much atmosphere into such a tiny cartridge. You start off in this shadowy world where every enemy feels like it crawled out of an old Japanese ghost story—somewhere between a samurai flick and a nightmare. The first thing you’ll notice? The combat’s got weight to it. Swinging your sword doesn’t feel floaty or cheap; when you land a hit, you feel it.

It’s not just about slashing through demons, though. You’ve got these weird, almost ritualistic power-ups that change how you fight, and the bosses? Huge, screen-filling monsters that look like they were stitched together from woodblock prints. The music’s all eerie flutes and deep drums, like something’s always creeping up behind you. It’s tough, but in that satisfying way where every death feels like your fault, not the game’s. If you’ve ever wished Castlevania had more yokai and less Dracula, this is your game.
