I've recently acquired this game and have been playing it off and on. The innocent devils system is interesting, the "steal" component is both challenging and rewarding (very much like a puzzle, figuring out how to steal from a lot of enemies), and the "crafting" system is fairly interesting and varied.

As with all Castlevanias nowadays, it can be a chore to find all the items / components that enemies drop (or that you can steal) - but overall the game is pretty fun. The fact that you're not limited to just a whip (like LoI made it) is a big factor in making this game a lot more fun than LoI, which was pretty boring, I'll agree.

I like doing the punch move that makes Hector breakdance all around the floor - it's fun. You have to have at least the third punch weapon, though.
