Well, I would have linked you the Cinemassacre video of them playing it so you could have seen it in action, but apparently that as well was taken down.
I got a chance to play it yesterday and cleared all 3 dungeons that were available at the time, and while fun (I absolutely love the old 8-bit graphics games tweaked to run in 3D, they have this kickass living diorama vibe to them) I disliked the perspective of it as it was really easy to unwittingly get hit by enemies. It was fairly faithful though, despite the fact that it seemed a little easier to dodge Aquamentus' fireballs for some reason. Like they were a little bit slower or something.
HAH! Figured my browser cache probably hadn't been cleared yet and found it in their "extras" channel from my history! I'll just link it since some of their stuff can be a wee bit strong in the language obviously for here. XD
