Experimental LAN Support is now provided
In the settings menu you can change "Relay" connection setting to "LAN"
Both the host and clients will need to set the connection setting.
The join code will be the local host IP Address, which the clients will input.
Host will need to make sure no firewalls are set, and their computer is discoverable on the network.
