Also, Airships is now available through Desura. You can still also get it through itch.io and IndieGameStand. At some point, I should probably do the Greenlight thing, but I'm in no hurry.
Development on the next early access version is proceeding well. This version is mostly about bug fixes, improved performance, and subtle improvements to the user interface, and should be out by the end of April.
The next development cycle is going to be about adding new features, specifically a system for ship-to-ship boarding. You will be able to add barracks of air marines to your ship designs and command these marines to use their grappling hooks to board and take over enemy ships.
