Looks like someone has been playing a little too much Demon's Souls. Look at the bright side, it has nice hula girls.
This games challenge is spotty at best especially if it stays anywhere near the original 360 version. Certain boss battles were very challenging but in a cheap tacky you didn't spam that button enough times sort of way but the majority of the game itself was actually so easy it was boring. If you want that Ninja Gaiden experience I would suggest dusting off the old Xbox version as it was superior in every way save graphics.
Nice review, I myself am dieing already, at least in so far as wanting to get my hands on the game! This is a spiritual successor to the King's Field series but with all the advice everyone is giving about using Royal as a starter I will have to scrap my plans to make a homage character. Something about the game makes you want to take the hard road. Looking forward to your next entries!
