In many ways, Double Dragon II improves on its predecessor.
It feels like your attacks actually will connect with your opponent this time around, and while there are no more hearts to increase your moveset repertoire, you already have plenty of moves at your disposal, and there is no time limit to worry about anymore.

The problem comes with these three aspects:
- Some of the game's platforming segments, which feel very clunky to go through, considering you jump with both A and B buttons;
- The fact that the buttons for punching and kicking are reversed whenever your turn around, and considering that kicking now hits behind you, it makes it really difficult to hit enemies on both sides and having to constantly switch buttons just to hit in front of you
- And the fact that there some enemies that suck balls, like the ninjas, that are super difficult to actually hit.

Double Dragon II: The Revenge on the NES is an improvement in many ways, but it also has some problems the original didn't have.
Two steps forward, and one step back.
