This looks terrific. But it's Windows-only.

I think it's available on Steam which would mean you could theoretically use it on Linux with Steam's Proton compatibility layer.

Can that be tested before purchase?

Steam has a generous return/refund policy [0], so you could buy it, test it, and if it doesn't work request a refund.

It worked for me last year, and entertained a few of us for a good while. Been meaning to revisit.

Side note: Elite Dangerous is on offer at the moment and that has been the only thing to give me that unnerving sense of scale you get when travelling between systems.
