So the asteroid thing was just me being stupid. So my problem I am having with multiplayer. I get the game running and the server is up you the other person can't initiate the connection you can click on the connect to button but it never goes anywhere.
Found the glitch, the password prompter is invisible for some reason, I'll fix this in next patch.
Until then you can only connect if there is no password on the server.
Keep in mind that Adrorium is more like a prototype rather than a proper game and I don't usually have time to test anything more than the basic features.
