Tideheart

Tideheart is a narrative-focused underwater fantasy adventure centered around exploration, environmental storytelling, and fluid underwater traversal. Descend into the remains of a forgotten world where ancient structures, submerged ruins, and strange lifeforms hide the truth behind a long-lost civilization.
Built by the small independent team at Broken Tail Interactive, Tideheart combines atmospheric exploration, puzzle solving, and character driven storytelling into an immersive underwater journey designed to make players rethink what an underwater game can feel like.

Exploration

Swim freely through sprawling underwater environments ranging from sunlit reefs and abandoned facilities to deep ocean trenches swallowed by darkness. Every location is designed vertically, encouraging players to explore entire spaces from top to bottom.
Hidden pathways, environmental details, and optional discoveries reward curiosity and observation.

Movement & Traversal

Tideheart places heavy emphasis on making underwater movement feel fluid, responsive, and enjoyable. Especially the jumps! Momentum, verticality, and freedom of movement are central to exploration, creating an experience built around immersion rather than restriction.
Navigate tight ruins, drift through open waters, and uncover secrets hidden far beneath the surface.

Environmental Storytelling

The world of Tideheart tells its story through its environments. Crumbling architecture, forgotten machinery, abandoned research sites, and traces of those who came before all help piece together the mysteries buried beneath the ocean!
Every area is crafted to feel lived in, layered with history, and connected to the larger world.

Narrative

The core of Tideheart is made up by the bonds between two siblings who couldn't be more different but utilize these differences as strength to explore where no other merfolk has gone.
Az, our protagonist, is a scavenger in a world built on the remnants of something ancient and powerful. Scavengers are the ones who go where others won’t! Diving into dangerous ruins to recover lost technology, artifacts, and fragments of a forgotten past.
Sam, Az’s sister, on the other hand has eyes set firmly on the future. She takes what he finds and asks: “What can this become?” She’s a tinkerer, a creator, a problem solver and, occasionally, a bit of a problem maker. She sees the world not as it is, but as it could be.
Heavily inspired by classic exploration games Tideheart focuses on these two as they explore the true depths of the ocean they call home! The game’s character-driven storytelling is brought to life by animated films and projects that make up the team’s background as well as the atmosphere, emotion, and weight of the ocean and its history!
