I've not only heard of it, I've played it. It's seriously very, very fricking hard, or at least it was when I had a go at it. Dude was still working on it at the time, so gameplay may have been tweaked since then. If you're a good DK player, and ready for something more challenging, then you should go for it. If you stink and can't pass level 2 on the original, then forget it.
