Matchmaking Server Update: (08-March-2018)
The server costs roughly 50USD per month to keep alive, at minimum. This is not an expense I can currently afford, so I have included the server file in the project, so you can host the server yourself.
You will need to port forward before any hosting will work. You also need to change which IP-Address the game will attempt to connect to when clicking "Go Online".
To change which server you connect to, go to the appdata eltania folder and look for the settings file. There you can change the address to that of the computer hosting the server.
Please note, that this is just for matchmaking. To play online you can still just host it over the internet or local network, and have people directly connect to the lobby.
The main server may opened up again in the future when I can afford it.
