Both cool and cute. Go and play, it's really not just for kids!
The graphics are simply amazing, but what else would you expect from SquareEnix? There isn't an intro FMV, but you can live without it. The game is quite colourful which, combined with the good animation, makes gameplay very joyful.
You can control absolutely everything by using the stylus which makes this game very interactive. The controls respond greatly and are very easy to use. This game has three main spotlights: the mini-games, the micro-games and the pop-up duels. The mini-games are what you need to complete to advance in the simple acceptable plot by entering books and complete their epilogues. Throughout the gameplay, you'll find certain micro-games, which you may choose not to play, but will certainly make a little effort to win more cards. And these cards I just mentioned are what you'll use in the pop-up duels, which are battles played with cards that have the power to summon a certain creature to perform a certain attack. If you play the Final Fantasy series, you'll recognise all of them. The battles are simple and quite well built, but you'll only need to enter the fray about 7 times throughout the whole game. Of course, you can still go back and have rematches, but it's not compulsory.
The rest of the game is really just walking about the cute little world. You'll visit a volcano, a forest, an underwater temple and a very strange tower. And of course, the chocobo farm. This game is aimed at very young people, but it's practically impossible to let this game in the store, even if you are extremely adult. The game is very cute, the mini-games plot is based in stories that most people heard about (adapted to the SquareEnix world) and can become challenging and fun to play. I guess you'll just particularly miss a deeper and longer plot and perhaps a more original one, since SquareEnix goes around the same stuff too many times.
P.S.: Be careful when saving, because you won't be asked for confirmation!
