Absolutely Frustrating
I haven't played a game so delightfully aggravating since the first time I played Mario and Zelda. You can get to the last dungeon without breaking a sweat and still lose everything in a matter of seconds. This is how gaming used to be, and how gaming should be again - you get a taste of accomplishment then a full-blown challenge that'll kick your ass into the dirt.
Now if only it could find it's way onto Android...
