Play Time Diver Eon Man (Proto) Online

Time Diver Eon Man (Proto) is an unreleased prototype for the Nintendo Entertainment System, developed by Atlus. It exists as a curious artifact from the late NES era, a period when developers were pushing the hardware's limits with more complex action and exploration concepts.

You control Eon Man, a time traveler who swings a whip-like energy weapon across interconnected, screen-by-screen areas. The main goal involves navigating hazardous environments, defeating enemies, and gathering key items to progress through different time periods. Signature mechanics include using the whip for both combat and grappling across gaps, alongside a time travel function that shifts the entire stage between past and future versions, altering enemy placements and level geometry. The game is notoriously difficult, with precise jumps and relentless enemies demanding careful play. It feels like solving a brutal, moving puzzle where every screen is a test of patience and timing.
