I thought this was a bakeneko at first, the wild look would be perfect as they're usually cray cray. But alas, no whiskers so it's a Marten.
... a Marten is fine too.
Seems like the game is actually a sequel to the SNES game, with the bad guy returning. The coins collected can be used to unlock "extreme mode", whatever that is? Maybe the end bit from the trailer where the boss turns into a hard mode variant.
Turns out the big tiddy goddess is
Ame-No-Uzume, the shrines patron deity & Saya-chan's ancestor. The thunder marten/raijû & resurrected female samurai were rescued by the heroes in the first game.

Hope they remake the SNES version of Harvest Moon next. It would be the finest looking game in the series since... the first one.
(Yes, I know the whole harvest moon/story of seasons rights issues & drama, everyone fucking know about it by now.)
