Even more troubling is the difficulty curve, which is less a curve than a sheer rock face. For hours, enemies will be minor nuisances, only to suddenly become able to kill you in a single hit after a certain point. It's possible to grind somewhat for HP, but not to any helpful extent. Joystiq came across a boss that they couldn't defeat, and just set the game down after about thirty tries.
Which is a shame, because during the good parts -- essentially, when it was at its most linear, and sending me from fight to fight with minigames interspersed -- it was absolutely thrilling.
