6 million years later I post here once more.
Here's a small progress report:
S2-1, S2-2, O2-1, and 2-3x are fully completed. O2-2 is very close to completion. Writing for the first half of act 2 is also very close to completion.
Thanks to a (semi-successful) blitz we tried, everything but O2-4 at least has unit placements done and just needs the beginning, middle, and ending events to be done, which helps quite a bit.
Most of the portraits are done, we're also redoing the griffon knight animation and adding a promotion option called the Arbalest (this replaces the kinshi knight we were intending to have).
