Below Zero has been in early access for the last two years. I haven't played it yet because I like to wait until games are out of early access. Yesterday, the announcement came that it'll leave early access in May. I'll probably get Breathedge and play that in the meantime.
BTW, since you're on PC, I found that a couple of mods make things easier for Outer Wilds. One is AutoResume, which skips the intro logos and animations and automatically resumes your expedition, getting you into the game much, much faster. Another is SmoothThrust, which helps if you play with a keyboard by steadily increasing thrust as you hold down the keys (simulating a controller stick, I believe), instead of going full blast from the start. That especially helps with the anglerfish, which I could not get past before, since any thrustering woke them up.
