The game is compiled for wasm32-unknown-unknown and loaded into a fixed 640x460 canvas centered on the black page by index.html. Browser settings and a fallback copy of the high-score table are saved in localStorage; native builds continue to use their normal per-user save file.

The page includes the official Macroquad browser loader locally. The WASM bootstrap is local as well, so the page does not require inline or third-party JavaScript. The web page must be served over HTTP rather than opened directly from a file: URL.

For a strict Content Security Policy, allow script-src 'self' 'wasm-unsafe-eval' for the browser's WebAssembly compilation and connect-src 'self' for the local WASM and optional high-score API requests.

When the same-origin /api/highscores endpoint is available, the browser loads and submits the shared top-ten table there. The small Axum service and an nginx proxy example are in highscore-server.
