**Lantern Valley** is a cozy miniature adventure for the browser with **over 16 hours of gameplay** between missions and side quests. Explore a tilt-shift valley of wind-swept grass, drifting autumn leaves and purple shadows where **Tina**, a young apprentice knight, hunts the **Sparks** that scattered before the Night of a Thousand Lights. Relight the Great Lanterns of every village and carry the flame back to the lighthouse, on **desktop and mobile**.

Swim across the lake, pet the dogs and cows, double-jump into a pirouette and **fly on the helmet's little wings**. Go fishing, plant a garden that grows while you sleep on a bench, cook by the campfire and mend a boat to sail through the mist to **five islands**. A full **day and night cycle** lights the village windows and wakes up Sparks that only appear after dark.

Under the hood: **Three.js** on **WebGPU** with an automatic WebGL2 fallback, **TSL** stylized lighting with SSAO, bloom and depth of field, over a hundred thousand grass blades, chibi characters driven by **procedural animation** and a **quest engine** behind the story — with dynamic resolution and a sharp upscaler to keep it smooth on phones.
