Glad you liked it :)
The demo was released as a completed project (so far). Since I didn't get the funding I needed to focus on the game and produce the whole thing, development for the rest of the parts has been shelved in favor of focusing on real life. So unfortunately the full game won't be up for sale any time soon.
More details are coming in an update along with a small bugfix patch for the versions of the game I can compile for right now.
