The stunning presentation shows what the DS can really do. But while Avalon Code has some great ideas, the execution is horribly, horribly flawed. The Book of Prophecy is poorly designed; it turns an innovative concept into an annoying, tedious, headache-inducing chore. The bland challenges and cluttered menus don't help much, either. It's a shame to see a game with so much potential screw itself over. Here's hoping the new world offers something better.
