Hi!
As for now, we're not planning to make a Linux specific version of the game.

What you can try is to open Steam, and in Settings>Compatibility turn on "Enable Steam Play for all other titles", this will allow you to play all Windows games.

I've tried it on my Linux laptop and the game starts just fine. There may be some issues along the way, though.

Cheers!

I've just played the demo on Linux (Proton Experimental) without a glitch.
I expect the same for this one.
