I think they mean is there a sequel planned (or other games in the same universe/series).
Well, I can't speak about anything specific or definitive, but we're always thinking about future endeavors and how to proceed forward.
In other words, if anyone wants sequels/stories in this universe to go foward; this game has to turn enough of a profit to warrant covering costs ;)
Perhaps the devs can consider crowdfunding their next game so that they can mitigate their out of pocket costs for niche games like this. :)
