It's not quite ready for any sort of early access release just yet and won't be for quite some time.
I'm not sure I want to do one either but we'll see.
I'll be trying my best to keep supporting linux. :)
Instead of an early access, when a demo that you feel comfortable enough (Maybe near release) is ready, release a demo in steam with the page (No early access). That would be really cool.
I will be making a Steam page at some point and likely putting a demo there as well.
And this naturally answers the other potential question, yes, the game will be on Steam at some point. :)
