NG:DS is a lot of fun, but challenging. They took some ideas from Ninja Gaiden 2 with the recharging health meter and took out potions. It makes for a more accessible game but you can still lose your life if you're not careful. With the touchscreen there are times when you won't get your desired move, but it's only about 5% of the time. For anybody wanting a good hack and slash on the go pick up Ninja Gaiden: Dragon Sword.
