Their September update post:
"I think there's a goodly number of heroines now. At this point, there's only a couple of plotlines left, before I'm ready to declare the game Complete.
(Which, to head off the questions in the comments—doesn't mandate that we then stop development on the game)
Those long-foretold plotlines are:
-Male Independence Faction
-Claumetria
-Renee
......and that's kinda, it? If we finished only those, I think I would feel whole. It's strange to think about. We made it, fellas.
Anyway, we'll be in touch re Hypnoqueen; hope to see you soon.
Sacha Witt
and everyone on the FutaDomWorld team."
In other words, they believe the game is nearly complete.
I still think Shauna needs a route (feels like a waste seeing her sitting lonely on the park bench) and some routes need more fleshed out art however.
