About this game
Run through the depths.
Recover the relics of a lost civilization.
PIECES OF THE DEEP is a roguelite action game built around auto-running exploration, where split-second decisions determine survival.
You play as Nyarmar, a small creature who lost its home in a massive seabed quake.
Rescued by a team of surface-dwelling explorers, you repay their kindness by helping with dangerous deep-sea expeditions.
■ Procedurally Generated Dungeons × Instant Decisions
Each dungeon is procedurally generated.
Your character runs forward automatically—your role is to dodge hazards, defeat enemies, and choose branching paths while pushing toward the depths.
Simple controls, demanding judgment.
Every moment matters.
■ Recover Relics and Expand Your Base
At the end of each dungeon awaits a powerful boss.
Defeat it to obtain relics left behind by an ancient civilization—materials and incomplete blueprints scattered across the seabed.
Back at base, recovered relics are analyzed and used to restore advanced technology,
unlocking new capabilities for even deeper dives.
Explore. Recover. Grow stronger. Dive again.
■ A Story from the One Who Retrieves
You are not the one who deciphers the past.
You are the one who descends—again and again—to bring something back.
This is not the story of a hero who saves the world,
but a record of those who recover what was lost.

[Devlog] 5 Ways to Power Up Your Player – Guided by Kyle!
Hello, this is CoMu. We are currently in the process of submitting the demo version for Steam review and are steadily preparing for its release.In this update, we will explain one of the core gameplay cycles: "Player (Nyaruma) Upgrades." In this game, you can use resources collected in dungeons to improve your abilities through Kyle, the upgrade specialist at your base.1. Max HP UpIn the harsh deep-sea exploration, survival is the most critical factor. By upgrading, the "Hearts (Durability)"displayed on the screen will increase one by one. Since your HP carries over between floors, the more you have, the better. It’s a priority to boost this before heading into deeper areas where enemy attack patterns become more complex.HP up2. Attack Power (Dash Tackle)While the game features auto-run movement, you can accelerate by pressing the directional arrow in your path. By increasing your Attack Power, you can defeat enemies and break certain gimmicks with a "Dash Tackle" when your power exceeds the enemy's level. Improving this doesn't just clear enemies—it speeds up your entire exploration.Attack Power upDash Tackle3. Pick-up Range ExpansionThis feature supports efficient resource collection. Upgrading this increases the magnetic range that pulls in itemsdropped around you. It allows you to automatically collect materials slightly off your path, significantly reducing the stress of exploration. Since player upgrades are performed using "Coins," improving your ability to collect them makes everything else easier.Pick-up Range up4. Bag Capacity (Material Storage)There is a limit to the number of "Materials" you can carry back from a dungeon. By expanding your bag, you can bring more materials back to your base. Note that "Coins" have no carrying limit—you can collect and bring back as many as you find!Bag Capacity up5. Stamina (Dash & Slow Duration)This status affects how long you can maintain acceleration and deceleration. Upgrading Stamina extends the duration of your das...Read full article on Community Announcements (SoU)AnnouncementsOfficial
