This game seems to be in an infinite alpha stage. I tend to check it every year or so, and it always has something new and interesting, but it’s about as far from a release quality as it was many years ago. The game is actually great, though. I used to play it on my PS4 last time, but it looks like console versions have been abandoned for quite some time. PC build appears to be maintained, and it slowly gains new features. It also has a decent Linux support too.
