Play Fushigi no Umi no Nadia (Japan) on sega Online

Fushigi no Umi no Nadia came out on the Sega Genesis in 1991, developed by Gainax. It's an action platformer based on the anime of the same name, and it fits right in with the kind of licensed games you'd see on the system back then, with colorful graphics and straightforward level design.

You play as both Nadia and Jean, switching between them to navigate stages filled with enemies and environmental puzzles. Nadia uses a wrench for close combat, while Jean has a slingshot for ranged attacks. The goal is to advance screen by screen, avoiding hazards and defeating foes, with some light exploration for key items. The pacing is brisk, though the difficulty can spike in later stages. It feels like stepping directly into the show's adventurous, slightly quirky atmosphere.
