Eden

EDEN — An Evolution

An underwater evolution game, played in your browser. A spiritual successor to a certain classic about climbing the tree of life — built as a love letter to it, right down to the title screen.

You begin as something small and barely-formed in the shallows. You eat. You grow teeth. You reshape your body, descend into colder and darker water, and fight the things that rule each depth — until you rule it instead.

🧬 Choose your ancestor

Three starting lineages, each pulled from the real Cambrian fossil record — and each one plays differently:

• Vertebrate (Pikaia — the first fish) — the balanced all-rounder. Signature move: Frenzy, a burst of speed to close the gap and strike.
• Arthropod (Anomalocaris — the Cambrian's apex predator) — armored and relentless. Signature move: Brace, soak hits at a quarter damage while you stand your ground.
• Cephalopod (Nautiloid — the mind of the sea) — fast and fragile. Signature move: Ink-jet, blast away in a cloud and become briefly untouchable.

Same primordial sea. Three completely different paths through it.

🦴 Evolve

Spend Vitae to reshape your body part by part — bodies, jaws, fins, and tails, each with its own look and stats, across five tiers of evolution. Bank Essence at your Nest for permanent upgrades that survive death. Every lineage has its own full evolution tree, so no two climbs look alike.

🌑 Descend

Four zones, each colder and stranger than the last, each guarded:

• The Reef Shallows — where you cut your teeth.
• The Deep — a bioluminescent vertical shaft, and the Bloom Queen.
• The Abyss — an open black expanse ruled by the Tyrant.
• The Sunken Graveyard — shipwrecks, whale bones, and the Gravekeeper, an ancient giant octopus you have to dismantle arm by arm.

📺 Built like it's 1994

• A real title screen — E.D.E.N. wakes from the dark, the theme swells, and you're in.
• Pixel font and chiptune sounds throughout — all synthesized live in code.
• An optional CRT scanline filter for that tube-TV glow.
• Full keyboard navigation with blips on every menu.

🎮 Controls

• WASD / Arrows — swim
• Shift — dash
• Space — bite
• E — evolve
• Q — your lineage's signature ability
• Menus navigate with the arrow keys + Enter

A note: Eden is an evolving prototype, built in Three.js and developed in the open with AI assistance (code, audio, art, and text). It updates often, and player feedback shapes what comes next — there's a feedback link right inside the game. Thanks for diving in.
