Marvelous: Mouhitotsu no Takarajima

Top-down adventure game where you control a group of kids searching for Captain Maverick's hidden treasure on a puzzle-filled island. You'll switch between characters to solve environmental puzzles that block your path forward, using each kid's unique abilities to progress. The island is divided into distinct areas, each requiring you to figure out how objects interact and which character can manipulate them. A rival pirate crew is also after the treasure, adding time pressure to certain sections. Expect inventory management, switch-based obstacles, and logic puzzles rather than combat-heavy gameplay. Originally released for Super Famicom in Japan only.
