As one of the biggest God Hand fans on this forum, and someone who pimped that game a lot when it didn't get it's due, I can honestly tell you that this game is not like God Hand at all. If you want a comparison, think of Dead Rising. It's not so much about murdering everyone, it's about chaining together kills to get a higher score, which in turns makes the level progress faster.
Basically, you are dropped into an open level where not everything is opened to you so far with the goal of unlocking the boss to fight. To unlock to the boss you need to complete a series of tasks, often times it's getting a certain amount of points to do this. So, the challenge isn't so much that it's hard to beat (it does ramp up even on normal, never close to God Hand level, nor does it even have the fluidity in controls) but being able to properly chain killings and attain a higher score.
I don't think that they have been doing a good idea of explaining what this game actually is, which is why there is a lot of misconception.
