MICROSEAA LIVING LITTLE WORLDMICROSEAA LIVING LITTLE WORLDGrow a tiny cell into a unique life form in a luminous 2D microscopic ocean. Feed on plants or prey, evade larger hunters and assemble twelve types of mouths, tails, armor and organelles. Explore five seeded waters and six life phases with eighteen AI species that hunt and flee among themselves. Three difficulty settings, local journey saves, encrypted backups and an unlockable endless ecology. Arrow-key swimming on desktop; right joystick and left dash on touch, with portrait-first phones. Sound starts off.
desktop, tablet, mobile. Single-player survival. No human multiplayer.
Arrow keys swim relative to the screen; diagonals are normalized. Space dashes. Touch uses the bottom-right 360-degree joystick and bottom-left dash, with multitouch and complete cancel/focus/resize cleanup. Phone portrait preferred; landscape/tablets work. Feeding and close attacks are automatic at the actual mouth. Omnivore, plant and predator mouths have different diets. Whole swallowing needs 25% more biomass and sustained unarmored mouth contact. Components include three mouths, flagellum, cilia, spines, directional shell plates, poison sac, electric cell, lens spot, energy vacuole and repair sac. Twelve types, three levels, real mounting restrictions and a six-to-eighteen-point capacity. DNA unlocks/upgrades, free mounting, mirror and undo, three named body plans. Evolve at a biomass milestone, or freely reassemble at a safe haven; danger prevents editing, the ecology pauses, and feeding cancels short exit protection. Five seeded waters, six phases and eighteen AI species; plants can complete all phases. AI prey on each other, and active hunters are bounded with mobile-visible perception and edge warnings. Algae conceal slow creatures, currents move them and crystals collide. Normal death retains completed evolution/blueprints and loses 20% unsettled biomass. Complete the final phase to keep freely exploring or unlock a separate endless challenge with capped ecological pressure and local score/time records. IndexedDB stores map, RNG, profile, components and three plans; portable AES-GCM encrypted JSON export/import validates and previews before confirmation, fully local. Pure-client encryption cannot prevent expert tampering. Esc/P pauses, M or Sound opts into audio; every load starts muted. No accounts, online multiplayer, gameplay APIs, Workers or cloud saves. Language is supplied by the portal; only portal game-entry clicks are logged independently. Static Web Analytics remains allowed. Components can be tapped or dragged to compatible mounts; drag the specimen to rotate its preview. First observations reward DNA and record relevant blueprints; glowing relic bubbles provide DNA and discoveries, while milestones guarantee core blueprints.
Yes. Unlock twelve component types, attach them at compatible mounts, upgrade them through three levels and save three body plans. Capacity, direction and energy create real tradeoffs.
Yes. All five waters and six phases can be completed using plant food and milestone blueprints. Predator, plant and omnivore mouths support different feeding styles.
No. Maps, evolution and body plans save to this browser in IndexedDB. Export/import encrypted JSON backups locally; there is no account or cloud save.
Free to play. No downloads or sign-up. Sound starts off; enable it manually.
