Its a bit of a mystery, it seems like the dev was never all that active, taking months between social media updates.
The dev said they were working on a major update to the game itself and that it would take a very long time. But that was around 6months ago. But before that it was 6months before their last major post, and ~4months before the major post before that. There are some that hold hope, other's that are pretty sure he got his kickstarter money 6months ago and ran.
