Hey, Liam. Thanks for your interest in my game.
I'm not sure if you're familiar with Unity, but it makes building for different platforms super easy. The only thing is I don't use Linux and I'm not 100% confident I'll be able to get it running, or troubleshoot issues that may pop up in that build specifically (if there happen to be any).
That said, I've gone ahead and uploaded a Linux build anyways. I'm expecting that it will just work, but I'm going to try to get Linux going for myself right now so I can try it out.
