Mechanics: Low in crunch, with the ability to be entertaining the key to success. Easily understood and used. I personally prefer more mechanistic games, but this looks idea for the people who like to concentrate on colourful description of speedy action (and in fact vivid and creative description of action is the key to winning).
Worldbuilding: The mechanics are good enough but not quite my cuppa. But the middle third of the book containing various faerie locales would be a valuable addition to any fantasy or superhero campaign whether you use the game system or not.
Adventures: There are three adventures at the end, the first being an "Arabian Nights" styled attempt to help a dreaming mortal artist seek out inspiration, the second being the discovery and attempt to foil a villain who is part fairy tale, part James Bond Villain, and the third being a rewritten version of the classic fairy tale "Donkey Skin" that I find to be a considerable improvement.
All in all this is a great package, and I can recommend it to you.
