Current estimate is somewhere around 25-28, but it may end up a bit longer depending on how the rest of the chapters go. The polyamorous routes will be added after the main game and the solo routes are finished!
No plans for that one, I'm afraid! All the polyamorous routes (A/R, A/X, D/X) are all mutual triads, but D and A are not interested in each other romantically so it wouldn't work out.
