Final Product: Lumin
Cover
The 16:9 key-art cover: a golden-hour garden clearing, a twig-and-moss nest, the keeper’s cottage and six founder Lumins — antique parchment storybook illustration.
Gameplay
Live gameplay: the Home Yard at first light — Thistle and Fern are home. “Welcome to your garden!” Tap a Lumin to open its profile.
Gameplay
Live gameplay: the Breeding Nook — choose one adult male and one adult female; their colours blend and their traits pass down.
Gameplay
Live game screen: six travellers wait at the gate. Pick a male and a female with visible body colour, eyes, nose, inner ears, ear type, tail type and coat.
A peaceful enchanted garden where small alien creatures called Lumins are collected, bred and raised — colours blend, traits pass down through families, and every egg hatches in its own time.
Lumin is a playable, browser-based cozy creature garden. Its first Lumins arrived as founders — strangers with strange colours — and they have been waiting for someone to care for them, to pair them gently, and to see what their children will look like. Choose a founder pair, breed them in the Breeding Nook, wait for the egg to warm, and hatch a baby whose body colour is the exact midpoint of its parents’.
Roam the Home Yard and the keeper’s House, grow a deep family in the Collection, track generations in the Journal, then keep breeding for new ear types, tails and coats. The garden remembers everything — nothing is lost when you close the page.

Game Features
- Live LLM Game Design — every part of the garden was directed by AI as it was built: the one-line seed became the world, the six founder Lumins, the modular sprite rig, the parchment art and the full breeding loop, designed and coded live until the game ran in the browser (deepseek-v4-flash real-time build). From one sentence to a finished cozy sim.
- Colour-Mixing Genetics — a hatchling’s body colour is the exact RGB midpoint of its parents’ body colours. Pair a magenta Rowan with a green Fern and you can predict the child before it hatches.
- Seven Inherited Traits — eye colour, nose colour, inner-ear colour, ear type, tail type and body pattern are each inherited from one parent, alongside body colour. Parents are saved on every Lumin, so whole family lines stay readable.
- Egg Lifecycle with Real Timers — breeding creates a persistent egg with one of eight visual variants. A countdown warms it (five minutes in the prototype), the egg becomes hatchable, and only your Hatch press releases the baby. Timers keep counting if you close and reopen the page.
- A Living Yard & House — up to six Lumins roam the illustrated garden with gentle idle movement and depth scaling — further Lumins sit smaller and behind, closer ones larger and in front. Click any Lumin to open its profile; step through the cottage door into the House.
- Collection, Journal & Browser Play — a paged 12-per-page Collection with filters (male, female, baby, adult) and sorting by newest, oldest, name or true rainbow body colour, plus a Journal of breeding goals. Runs entirely in your browser, no download — save, close and return to the same garden.

Production Process Breakdown
Stage 1: World Buildingclaude-opus-5
From the one-line seed “Lumin — a cozy creature garden” the AI built the world: a peaceful enchanted garden whose founder Lumins arrived as strangers with strange colours, plus the overview, tone, era and the Classic Fantasy Parchment visual style that governs every asset.

Stage 2: Creature & Sprite Artgpt-image-2
The AI designed the Lumin species — a blend of fox, cat, ferret and gentle alien — then generated the parchment scene backgrounds (Home Yard, House interior, Breeding Nook) and the modular adult and baby creature art: body, ears, tails, eyes and coat patterns kept as separate transparent layers.

Stage 3: Genetics & Game Codedeepseek-v4-flash
The inheritance engine was coded live: RGB-midpoint body colour, one-parent inheritance for eyes, nose, inner ears, ears, tail and coat, parent IDs stored on every Lumin, eight egg variants on a real timestamped incubation timer, and a persistent save that survives a page reload.
