You are reviewing my browser game for web deployment and Buncha Games readiness.

Read first:
- https://bunchagames.com/developers/docs/optimizing-for-web
- https://bunchagames.com/developers/docs/uploading-games
- https://bunchagames.com/developers/docs/all

Tasks:
- Identify the engine, build command, output folder, and Buncha Games upload target.
- Build or inspect the production browser export.
- Run a size audit on the final output and list the largest files.
- Identify optimizations already implemented.
- Identify safe high-value optimizations still recommended.
- Check Buncha Games packaging: index.html at ZIP root, no source/editor folders, no secrets, no node_modules, no server-only files.
- Check desktop iframe readiness and mobile readiness only if mobile support is claimed.
- List connected services or external hosts found in the browser build.

Return:
- engine and build context,
- current output size and largest files,
- optimizations already implemented,
- recommended optimizations by priority,
- Buncha Games-specific readiness notes,
- commands/tests run,
- blockers or manual QA needed.

Do not upload, submit, publish, or edit the Buncha Games platform repo unless I explicitly ask.
