This is an awsome game! This game should belong to every DS owner. Its easy at first but then harder and harder and harder. You get to play with another N+ owner. Or just play single player. The single player has ... um like levels inside a level. For example 1-0, 1-1, 1-2, 1-3. Kinda like Super Mario Bros. and other Mario games.
Multiplayer you play with another N+ owner.
There is also level editor. This mode you make your own levels. There are tons of exciting levels on single player mode.
I didn't know anything about this game before renting it, so I went in fresh. I instantly loved this little game. It is a nice strategy/action game. Simple graphics, but addictive and a little frustrating at times. I had to keep this little jewel so I selected the Keep It button - and for $15 bucks, you can't go wrong for hours and hours of fun. Give this one a shot.... I bet you'll like it!
