The Dev has done very little with the game in quite a long time, despite being occasionally active on their Patreon. The only answer anyone really has is "maybe". Its not absolutely dead, but who knows when we'll get actual new content.
They could have at least finished the story, even rushed, before starting the other project, although I can understand the need for some variety, especially if the alternative is burnout, now there's two unfinished projects dead on their tracks.
