The game was released yesterday in Japan, and someone already loaded a straight run-through. For the most part the game takes most inspiration from Bloodlines (no problem, since that's a great game), with plenty of tips to the rest of the classic series (got to love the map screen being like 1's (along with the opening using screen captures from 1)). Coolest thing is that the whip can upgrade past the long chain and into the ability to launch fireballs from its tip (which was apparently a feature of the games featuring Christopher Belmont).
Anyway I can't wait until this game is released in America, but in the mean time the previously mentioned playthrough can be seen here:
