Hearth v1.2.0

Hearth v1.2.0 — the agent-native 2D game engine.

Desktop app: download the build for your OS below.
macOS first launch (builds are ad-hoc signed, not notarized yet): if macOS blocks the app, click "Done" (not Move to Trash), then System Settings → Privacy & Security → "Open Anyway". On macOS 14 and earlier, right-click Hearth.app → Open also works. If macOS says the app "is damaged", clear the quarantine flag: xattr -cr /Applications/Hearth.app.

Agent tools (no install needed, any Node ≥ 20):

• node hearth-cli.mjs --help — the full hearth CLI
• node hearth-mcp.mjs --project <your game> — MCP server for Claude Code / any MCP client
• hearth-player.js — the web-export player; keep it next to the CLI (or set HEARTH_TOOLS_DIR) so export web works
