# ThicketScript

> ThicketScript is a language built from the ground up to make games. It has TypeScript-like syntax, its own type system, a VM and `.tbc` bytecode. One program, `thicket`, runs, checks, debugs and builds your game. It is free to use, with no royalties.

The docs below are the source of truth for the language and its built-in modules; the willow, willowui and gamekit portals document the 2D module, the UI toolkit and the game-structure package. For agents working in a ThicketScript project, `thicket mcp` is a built-in MCP server (stdio) that answers diagnostics, module APIs and symbol lookups for the version installed; setup is on the AI agents page. The whole docs set as one plain-text file: https://thicketscript.com/llms-full.txt
