We can say part of the art direction is done in Japan, but we cant say who. You can guess as much as you want!
There's no way it's not George Kamitani.
And any game with music by Sak
imoto is an instant buy for me. Gameplay and art is looking great too, so this sounds like a winner.
I really hope this gets a retail release, but coming from an indie dev, it would really surprise me unless they get a publishing deal.
