Play Phantasm (Japan) Online

Phantasm is a 1990 Game Boy release from publisher Pony Canyon, a side-scrolling action game that fits right in with the platform's early library of dark fantasy and exploration titles. It doesn't try to reinvent the wheel, but it carves out its own niche with a distinctly somber, claustrophobic atmosphere.

You control a lone knight navigating a labyrinthine castle, room by room, clearing each screen of enemies before you can proceed. Your main objective is to find and collect four crystal shards to unlock the final confrontation. The combat is simple, relying on a short-range sword slash, but the cramped quarters and enemy respawns keep the pressure constant. The pacing is deliberate, almost methodical, as you backtrack through familiar halls now repopulated with foes. It feels like cautiously mapping a haunted space, where every corner turned is a minor act of courage.
