Play Hercules no Eikou - Ugokidashita Kamigami (Japan) Online

Hercules no Eikou - Ugokidashita Kamigami came out for the Game Boy in 1992, developed by Data East. It was part of that wave of action-adventure games that tried to capture the feel of bigger console titles, but built for on-the-go play. You don't see many games diving into Greek mythology on the system, which made it stand out just by its setting.

You control Hercules, moving screen by screen through temples and overworld areas. Your main goal is to rescue the gods, who have been turned to stone, by defeating bosses and solving environmental puzzles. You use a club for basic combat and gain special god powers, like Poseidon's ability to create blocks or Hermes' winged boots for higher jumps, to access new areas. The pacing is deliberate, with some backtracking, and the difficulty can spike during boss fights. It feels like a thoughtful, sometimes challenging puzzle box dressed up as an action game.
