Cancelled due to lack of interest from the developer. Perhaps moving to a new home, not having an internet connection and temperatures hitting 39'C contributed, but mostly I just didn't like the project at all. It has been moved to the bin.
The new plan is to make a 'full game' instead of a quick demo. Something I can enjoy playing and sell to others that might also enjoy it. I will document the process here on this blog, and will maintain a progress log in the form of a kanban style overview for non minor progress. Tracking progress in this way ought to keep me honest :).
Information on the game itself will be forthcoming, but the kanban already has some dry details.
