I'd love to have a native build, but it's really hard to justify the extra development time, and I'm a solo developer - which means trying to keep multiple OS builds working is very hard and a huge drain on my time (learned that the hard way with the Mac build that's already falling behind the Windows one).

But, I hear only good things about Proton these days, which would let you play the Windows version under Linux with little trouble, probably. That's probably the safest bet for getting Slipways on Linux. If you buy it and it turns out you can't play it that way, I'll be happy to refund it.
