And that could be whole content of this post.
What to say more?
Demo is generally current state of the game at the time of writing. Less some later-game content (that was already made). Also hierarchical grid features, that were mentioned in previous post, were not needed for demo campaign and so were omitted.
From now on, most effort goes to final game.
But do not worry, demo will get updates.
With bug fixes primarily.
And if we find some way of using new mechanic in limited scope of demo, it will be added there too.
So stay tuned for updates.
