From the Nikenme Radio stream (Jun 19): AoCF's design phase has recently concluded, moving into full production.
The initial plan for AoCF was to have the demo out at Winter Comiket 2016, and full release at Reitaisai this year. The entire schedule was delayed to develop ULiL for PS4.
Some other tidbits:
- In the early days ZUN longed for the live performance experience, and deliberately made his music to have that "live" feel. He no longer does that.
- The fighting game themes are especially long due to the gameplay, and harder to write.
- He has been playing EoSD and other older games, and now finds them very user unfriendly.
