I bought it and went straight to the instructions to figure out how to play, and I was kind of overwhelmed by the... length of the instructions. And it didn't strike me as being presented well. I felt like I needed a tutorial level or something to walk me through it.
I started a single player game and stuck with the archer because I had read the instructions for him. It seemed fun, but it didn't seem to be going anywhere. I tried on some other hats and figured out some of the basic controls, but after a while it was clear that no one was going to win so I quit. Haven't gone back to it yet, though it's a game that I think I'd like once I learn it.
It seems like a game that would benefit from a coordinated effort, which is hard to do on PSN where so many people don't have headsets.
