It sure does look nice. Did you view the blog with the 25 minute game view? You can see on-screen commands/options at the bottom as the recorded play moves along. But what is odd is that I don't see any humans. Just ships moving and firing. Kind of strange.
But the postings I saw seem to suggest that support and responses from developers is non-existent. In fact, the last seems to have been March 2015.
There are very nice features the developers want, such as players discovering the world, so no map. Like Tom's Explore! variant. There will be people, it seems, so the Youtube video is just an alpha demo, I guess.
But is this thing still alive? I don't know. Lots of questions on the user forum, though.
