When I played El Shaddai: Ascension of the Metatron at last year's Tokyo Game Show, I was told I was playing a toned-down demo version, the difficulty mellowed to allow the public to make its way through the demo.
That was not the case in the version shown during GDC this week. In fact, my avatar Enoch got his ass -- well-appointed in limited-edition Edwin jeans -- handed to him. But as he says in the event of his (near) defeat, "It's okay. No problem."
