Exactly what DS was built for! Finally a use for that stylus :)
Kids younger than my niece will enjoy this aspect but not sure about the difficulty issue. I'm at the half-way point and have hit a major roadblock. To finish the level I must climb a tree while battling tarbats and trying to keep my balance during earthquakes. To top it off, I've got to shoot down what look like beehives - 4 of them - but no matter how hard I try, I can only get to 2 before dying a horrible and naked death. (Yes, naked but not graphically so.)
Anyway, I'll keep trying but the frustration is setting in. Still, I think I spent $20 on it and it's been much more entertaining than some of the other DS games. Two thumbs up.
