Hey, is there by any chance on a native Linux version of the game, knowing there is a Mac port? Linux gaming is evolving faster than anyone has expected as of late, to the point Linux is set to outdo macOS in gaming market share. I am aware that Proton exists, though a native Linux port would be very beneficial for the Steam Deck in terms of battery life.
It's fully understandable if this isn't in scope though. Some support for Proton would be good if you opt to just keep the Windows build.
If anything, I am totally willing to help test such native builds, or even test the Windows build under Proton.
