Great to see that this is still worked on, love this game! IMO it's ready for steam EA.
There's a bug where the game screen will go black and need to be restarted if left in the background for a while (on windows), though I don't know how to reproduce it consistently.
There's plenty to say about balance, underutilized features and missing endgame contents (or midgame sometimes, would be nice to have starlifters :D ). But maybe it's too early for that kind of feedback? Let me know if you're interested.
