In the developer's words

Echo in the Lightless Deep is a deep-sea survivor roguelite. Symbionts fight for you; you steer, dodge and build. The brighter your core, the farther you see and strike, and the more the deep sends at you. Five giants guard the way down. At the bottom, choose: return to the light, or stay dark.From the game's page on Steam
