1. Navigate to server/ then run npm run server-run
2. Navigate to client/ then run npm run host
3. done

If any crashes encountered, restart the server (by rerun npm run server-run); logout all users, audiences, host and relogin (frontend doesn't need to be restarted) and reiterate the game manually (and pray so no more crashes gonna happen later on 🙏)

Frontend and backend running on different port, ngrok free plan does not work. Tailscale (or any local VPN services, or a telnet) is recommended to connect host, audiences and players machine together
