Fun game, makes you think a few times, but never so difficult you need to go to a gameguide.
Story, the story is actually good. Especially the ending
Gameplay - It varies a lot. Changing between characters is different and pretty fun, although I wish the characters would change faster. That way you could do a combo with three characters. The puzzles are different, and often require you to think about the unique abilities of the creatures you can change into. I recomend not pushing start and asking the book for a hint until you are truely stuck. Otherwise it takes the fun out of it. He pretty much tells you what to do. But it is nice when you are sick of running around and are not sure what to do. The combat could be a whole lot more fun if switching creatures was instant.
Sound - good stuff here. Graphics - almost a 10, almost. There are a few textures in the game that are blurry. They are far and few between. Why did they do that? They almost had perfect graphics, darn lazy devs.
