A little confusing at first, especially because the jokes aren't really funny (which is ok if they're not supposed to but you'd expect them to be) and they also don't correlate to the given information whatsoever, but you get used to it after a while.
While the description does have instructions (which I admittedly read after playing), I think you should be able to insert some sort of tutorial or instructions drive in the main menu so you can actually read it all from in-game.
All-in-all, it's a pretty good game. I liked it. I was *good* at it.
