Here we are, deep in the heart of this month's release. On top of the main story and all the side content, there's a lot of back-end code and cleanup, including continuity work to remove characters from stories if they've ended their story. This work will probably take us well into the final build (including little bits folks are still pointing out).
As a part of the End coding, we did have another look at the "math" of how you earn Qi from finishing stories. We did some tweaking so that you earn what was really intended when we first started, so if you've finished Saaya's story already, you'll be getting a little extra (which I'm sure you used to help Apollyon or Natalie). Mina, on the other hand, will only next you an extra 1 Qi. This might make Qi a premium earlier on if you replay the main story again.
This time around, there isn't a combination scene. There is one more left in the main game, but it'll be coming late and the way to unlock it's what I like to call Dark Souls obscure. There'll be more on that when it does become available. Of course, we may sneak in a few into the endings for some obvious pairings.

As mentioned in passing, we are working on a Story Replay Mode for 0.28.0 where you'll be able to play through any girl's story once unlocked. It'll involve all their story scenes, all the Other People scenes with them, and any combo scenes that may involve them.
Thanks for your interest and patronage,
