This game isnt very good. Right off the bat, it needs to be mentioned that the Wii doesnt need any more of these "tilt the controller to move the marble/monkey in a ball/mercury droplet/water drop" games.
Dewy has a little more going for it in the way of story elements than say Kororinpa, and it does offer some variety by letting you change into a cloud to electricute enemies or ice to freeze water hazards. But when you break it down the game just isnt all that interesting for more than an hour or so. The story is the telling of magical water droplet that is trying to save a withered tree from Blackwater (If I recall), and if you ask me, this is just an under-handed jab at the Blackwater Private Security firm protecting our leaders and diplomats from The Taliban and Al Quada over in Iraq.
Anyways, I'm pretty heated up right now thinking about the liberals trying to screw with these types of "happy land gummi drop saves the land" games, and then calling the enemy Blackwater.
The Wii needs more games where we can kill terrorists, race million dollar jet cars, or beat up gang bangers. I'm sick of the kids table menu.
