I bought and played it, but only for about 20 - 30 minutes. Not because it's bad, but simply because I have a biomechanics midterm tomorrow that I really need to study for (taking a quick break now, then back to it).
The controls work really nicely. The only two I'm a *little* worried about are the slashing and rolling controls. However, you don't start using them right away, there's a story to watch and it takes a few min to grab the sword. So I've had almost no time with them, and even in what little time I have played I was getting much better. All the other controls I've had to use so far work perfectly.
Overall, the game is fun, has good graphics, is easy to play, and oh yeah, is fun. Did I say that twice?
Take this with a grain of salt, because I'm *barely* into it, but from what I've seen so far it's really fun, and the controls work nicely.
