Play Little Master - Raikuban No Densetsu (japan) Online

Little Master: Raikuban no Densetsu came out for the Game Boy in 1991, developed by A-Wave and published by I'Max. It was part of that wave of early 90s portable games trying to capture the feel of console adventures in your pocket. You don't see it mentioned too often, but it has its own quiet spot from that era.

You control a young hero exploring a world screen by screen, fighting monsters with a sword and a bow. Your main goal is to find the eight pieces of the Triforce scattered across the land, which involves navigating dungeons and solving simple puzzles. The combat is straightforward but requires you to manage your positioning, and you'll spend a lot of time searching every corner for keys and hidden passages. The game moves at a deliberate pace and can be quite challenging, especially when you're low on health and trying to find the next safe screen. It feels like a thoughtful, sometimes tense exploration of a compact world.
