A lot of interesting stuff there. Sounds like a lot of care went into the sound and music design. The screenshot of the Switch 1 DKB prototype was cool.
One quote that stood out in particular:
Takahashi: There's a lot of leeway in terms of progression in this game. For example, locations or parts of the story you can skip without suffering any consequences. When the game progresses in a way we hadn't intended, we call it a “sequence break” in development terminology. Typically, in game development, restrictions are put in place to prevent this from happening, but since this game is all about destruction, we wanted people to play freely. Truth be told, restrictions make things a lot easier for us developers. (Laughs) But please do experiment.
We'll see how it manifests, but in general I like when they loosen up on the guard rails.
