Not just an april fool's joke, at least, not for the first two levels anyhow. First level is an opponent swordsman, second level is a green guy with a mace, and the third level is a yellow thief chick with some daggers. I wasn't able to beat her since she makes no noise until right before she attacks, so I could get one block off and then she was all the way on the other side of me and kills me. You can probably beat her, but I couldn't. Fun stuff, but I bet there is a part that becomes impossible where it's the april fool's joke, but I didn't get there.
