Wonder Boy III - The Dragon's Trap
神奇小子：III - The Dragon's Trap
Wonder Boy III: The Dragon's Trap is an action-RPG developed by Westone and released in 1989 for the Sega Master System. The game follows Wonder Boy as he explores various environments, defeating enemies and bosses while collecting items and upgrades. A key feature is the transformation system—the protagonist can assume different creature forms (dragon, mouse, hawk, lion, tiger, and cobra), each granting unique abilities necessary for solving puzzles and reaching new areas. The player navigates side-scrolling levels, managing health and equipment across multiple stages. Combat relies on timing and positioning rather than complex mechanics. Progression involves acquiring new weapons, magic, and forms to access previously blocked areas, creating a structure that rewards exploration and encourages returning to earlier locations with new abilities.
