Build without progress bars.
Change the game and keep playing. Routine changes reload without dropping you into a native build.
Find the fun faster.
Loop is the fastest way to iterate on a game idea.
Loop shortens the path from a change to useful feedback.
Share instantly.
Send a playable link as soon as an idea is worth showing.
Learn from every playtest.
Loop records the game state behind every frame. Scrub to any moment and inspect the entities, events, and values.
Work with AI on the live game.
Your AI tools can inspect the project and running world, make a scoped change, and verify the result. You direct the work.
Take the winner into production.
Build native Players and move performance-critical systems into C or C++. The prototype does not need to be rewritten in another engine.
Recordable ECS state
The running world stays structured, inspectable, and restorable.
Familiar authoring tools
Game data in TOML. Behavior in TypeScript or JavaScript. Interfaces in HTML and CSS.
Native power path
Move individual systems into C or C++ when they need it.
One command model
The editor, CLI, tests, and AI tools use the same typed commands.
Plain-text projects
Source stays readable, diffable, and compatible with ordinary Git workflows.
Exact build identity
Players identify the exact code, assets, packages, and runtime they contain.
Browser and native Players
Build the same project for immediate browser delivery and installed targets.
WebGPU and native rendering
One rendering architecture spans browser and native Players.
