Rendering / wgpu
A forward+ pipeline with hand-shaped post. Watercolor and pen-and-ink material presets ship in the box. Shader hot-reload in 40ms.

Chloe
An engine that whispers instead of shouts. Built slow, bound like a chapbook, pressed with wildflowers between the pages. Chloe is not a product — it is a person you write games with.
// engine boot sequence use chloe::meadow; fn main() { let world = meadow::seed( "a quiet place" ); world.grow(); }
§ 01 · philosophy
Engines matter because
games are gardens.
We built Chloe after twenty years of shipping inside engines that felt like warehouses — fluorescent-lit, optimized, airless. We wanted a place where a triangle could be a petal again.
Chloe is not fast because it wants to be fast. It is fast because a flower must open before the bee forgets. It is small because a seed is small. It is open because the rain is open.
Every engine has a soul. Ours is a woman in the meadow who stops to notice things.
You will write code in Rust, WGSL, or a small scripting language called chime. You will deploy to desktop, web, and handheld. You will, we hope, make something tender.

§ 02 · features
What the engine is,
in eight uneven pieces.
Audio / spatial_mixer
Binaural HRTF, stem-based music layering, and an "ambient weather" module that blends field recordings based on scene state.
Physics / rapier
Rigid, soft, and cloth — plus a novel "garden" solver tuned for vegetation, wind, and anything that sways.
Scene / ecs
Archetype ECS with a "seasonal" scheduler — systems can be tagged spring/summer/autumn/winter and cross-fade smoothly.
Scripting / chime
A Lua-shaped language with Rust FFI, pattern matching, and a REPL that reloads your running world without dropping the pointer.
Netcode / weave
Rollback-first with deterministic lockstep as a fallback. Sub-frame granularity. Designed for tiny co-op, not massive MMOs.
Editor / garden
The editor is a garden, not a file tree. Nodes are plants; systems are beds; and time is a slider you drag with both hands.
Deploy / press
One command to press your game into wasm, native bundles, or a handheld cartridge image. Signed, notarized, polite.

Chloe 0.9 "meadow" is available now. Read the docs, clone the repo, write a small tender thing.
Chloe is a seed, not a cathedral. Written by four people in three time zones. Licensed under the Open-Handed License. Type set in Dela Gothic One, Crimson Pro, IBM Plex Mono, and DM Sans. Hand-tended since 2024.
