Great puzzles and storyline, but just too easy, and little strategy.
The only problem is that it's easy and short. I've played the first game in the series and I was surprised to see no improvement in the battle system at all, and little strategy, and I think I would of gotten through it quicker, but I didn't discover how to set Djini to my characters more properly until the very last boss in the game, (the only one I failed to beat).
I think they could of added new strategic features and challenged a bit more, but the puzzle in the story line is worth it, and when you play it you'll get hooked into it.
