Kagerou Densetsu is one of those weird, obscure NES games that slipped under the radar—probably because it never left Japan. It's a side-scrolling action RPG where you play as a ninja, slashing through enemies with this oddly satisfying, slightly delayed sword swing that takes some getting used to. The music’s got that classic chiptune vibe, and the levels throw these weirdly specific traps at you, like disappearing platforms timed just wrong enough to make you swear under your breath.

At first glance, it feels like a standard hack-and-slash, but then you realize there’s this whole upgrade system where you collect scrolls to boost your attacks. The translation’s rough if you’re emulating it, but honestly, half the charm is figuring out what the heck you’re supposed to do next. If you’re into retro games that don’t hold your hand, this one’s a neat little time capsule.
