Submerged: Hidden Depths

Miku and Taku, a sister and brother, explore the remains of a city swallowed by the ocean. Miku has a mysterious power she hopes to use for good, and the pair work to clear a corrupting force from the ruins.

Sail between buildings and islands, then climb through ruined structures using automatic traversal. Solve simple environmental puzzles and carry seeds to corrupted sites to restore them. There is no combat or character death.

Explore the map for points of interest and collect diaries, relics, flowers, creatures, and boat upgrades. Main locations advance the story, while optional finds fill out collections and unlock visual customizations for Miku and the boat.

Reviewers often enjoy the calm, combat-free exploration and the atmosphere of the flooded city, especially its scenery and sailing. Collecting and discovering the ruins are also appealing to some players. Others find the climbing, puzzles, and collection loop too simple or repetitive, so the relaxed pace is not for everyone.
