The bangers just don't stop. This is another classic. They made many improvements throughout the second game, one of which was being able to climb upward or downward on walls rather than having to be stuck in one position or tap jump like in NGNES 1. Great game. I love the double-shadow ninja power that makes you feel so powerful. Being able to attack or evade and attack, then having the ninja just rhythmically slash whichever boss you're up to, such a great nes series.
