I'm sorry. There won't be a linux version anytime soon. We are working on a major engine update though - I'd love for you to try it out.
I will absolutely try it out once theirs a Linux version because from thee looks of it this is what I've been waiting for (and trying and failing to make in the game engine I use) and my computer meets all the requirements except the windows part.
We will do our best launching this on other platforms, we've been prioritizing our time on the tech - we are spread kind of thin at the moment...
