The Secret of the Blue Water

About

The Secret of the Blue Water is a point-and-click adventure game that follows a young girl navigating a mysterious submarine while searching for her missing father. Players solve puzzles and advance the story through pre-rendered video sequences and static backgrounds. The narrative leans into sci-fi mystery with a distinctly anime-inspired aesthetic. The game runs on obscure 1990s Japanese hardware but plays like a classic Western adventure in structure. This title showcases Gainax’s early experimentation with full-motion video and atmospheric storytelling. While not widely released outside Japan, it holds a niche reputation among fans of retro adventure games and the Nadia anime series. Its visual style and awkwardly charming dialogue reflect the studio’s later work, though the gameplay remains firmly rooted in early 90s PC conventions.
