Only two of us are actively working on the game, so unfortunately we cannot commit to a Linux version and maintain both PC and Xbox versions. :(
Thanks for the response regardless. Count me in for a purchase if you're able to do so down the road.
I'm on Linux - I bought the game here, then used the Steam key and played through Steam Proton without an issue. If that's an option for you, it might work!
It's an option but I have plenty of Linux native games on my wishlist that get priority over my money.
