It's really not in that state at a moment, and nothing is commented.
I will do more work on the engine itself, and want to redesign the console and connected interfaces first.
But if I get to a point to release the source I will let you know. If I would have classifed the current release it's a pre-pre-alpha. :)

I am of the opinion that all software that is publicly available should also have a publicly-available source. If it gets put on GitHub I could make a branch or fork and merge in the Linux compatibility tech if I got the time. A little effort for your audience increasing. If you won’t do that, I rescind my interest in the game entirely.
