Takahashi Meijin no Bouken-jima IV

Takahashi Meijin no Bouken-jima IV is a 1994 action-adventure platformer for the Famicom. You play as Master Takahashi, a straw-skirted hero, as he rescues his kidnapped dinosaur companions from a mysterious shadowy entity that brainwashes the island's animals and alters its terrain. The game features side-scrolling levels across six areas, each with unique environmental hazards, collectible items, and boss battles. Gameplay includes running, jumping, climbing, and using a variety of weapons and tools. It stands out as a more open Metroidvania-style exploration platformer than earlier entries, with an inventory system and password save feature. The story ties into the series' recurring cast, including Master Takahashi, Tina, and the dinosaur friends.
