This is a very strange game. I bought it a couple months ago, tried it, and didn't like it. I was confused by the interface, and basically had no idea what I was supposed to be doing. Just recently, I decided I'd give it another go, and after giving a little effort to figure out where I could go and what I could do, I found myself sinking quite a bit of time into it. I don't think its gameplay is very intuitive at first, but there's a free demo. Try it out.
Those who have played it, what are your thoughts? I still haven't tried multiplayer...
