It does, however, still work quite well with the Windows version via Steam Play Proton on desktop Linux and is Steam Deck Verified against the Windows version in Proton. So while it’s a loss of support for their Native build, it’s still fully playable on Linux.
Yeah, I prefer native if possible, but I understand that it’s not likely to gain much ground outside of the indie/FOSS community. Proton is a lifesaver, made switching over to Linux fully orders of magnitude less painful.
