Ninjatown does everything well for a tower-defense game on DS. The controls are precise and smooth, visuals pleasing and it even includes an entertaining and silly story. The game also offers fun in small chunks, as each map clocks in at about ten minutes. Thus, it's perfect for on-the-go gaming. Even so, a couple flaws hold the title back, especially the difficulty setbacks and rinse and repeat feel of battles. Weigh those issues carefully in deciding on whether or not to pick this one up.
