It's been a long time since the release of Star-Twine... 3 years in fact!
I am still working on the game. A major update is coming which will include, among other things, a single player campaign! This will make it easier to get into the game and learn how to use the different structures. It will also add more content and variety to the game, and give a better feeling of progression.
In addition to the campaign, the update will include lots of graphical improvements, a revamped in-game interface, an improved AI, better victory/defeat sequences and some gameplay changes and rebalancing.
I will start writing more regular updates from now on so you can follow my progress.
For now here is a video of a quick game against the AI:
