Void Mine could be one to watch, a zero-gravity narrative action adventure that has you explore a space mining station.
It popped up on Steam recently and the developer has now fully confirmed Linux support so we're good to go. The trailer (shown below) doesn't really show much but it looks like it has a good atmosphere.
It's not overly clear exactly what you will be doing or what you will encounter but from what I can gather, you will have no combat abilities. As you progress through ten levels, you will need to find hidden passwords to keep moving on with some dangers lurking in the dark.
Developed by the two-person Spanish team Eteru Studio, it's releasing on March 8th on Steam. Could be good, will take a look at release hopefully.
