Just updated and played again. I forgot to say its quite polished for a alpha and I found the controls a bit better from last time. However in auto pilot mode my ship flies into asteroids. Will there be any multilayer support? Right the now the game has a lot of promise, but the current crop of missions are not really doing it for me. I just end up flying around a lot and blowing up any baddies, rather than using fleet points and getting strategic.
As for dual monitor. In linux at least there may be no fix in many cases, since the drivers are reporting that there is just a single wide monitor. Its up to the user to config there xorg to report things properly i think (some setups this will not be possible). Nvidia has quite a bit on it. Long story short, you need to add extra mode lines to the xorg.conf. Otherwise there is talk of adding this more directly to lwjgl, but even then i think the sea of different xorg config options, it will be hit and miss. You could tell users to config their machines properly
if its any consolation, the vast majority of games and even many apps, don’t play nice on many monitor system under linux at least. As long as you support a windowed mode, your gold really.
