From Wikipedia, this is Oboro Muramasa Yōtōden, and I'm guessing the name will be changed if this is localized (Odin Sphere is apparently called Ōdin Sufia in Japan).
Also from ol' Wiki:
So far two playable characters have been specified: Momohime (百姫?), a young girl who wears a kimono and wields a katana, and Kisuke (鬼助?), an amnesiac ninja boy. Not much more has been announced about the game, though due to the obvious similarities to Odin Sphere it is presumed to be a spiritual successor.

Just think of the two control scemes as easy and hard mode.
A flashy-first game is awesome when it comes out. A great-first game is awesome forever.
