It's the second game for SNES.
Story:
Master Higgins and his wife Tina want to have their honeymoon on a float. But then they have an accident and get lost. Tina gets found by a king and gets forced to stay with him. Master Higgins just awakes on a beach and is searching for his wife. Then he sees how she gets kidnapped and of course he's on the way to find her. This sounds simple and it is, but every time you defeat a boss Master Higgins hears a voice, the voice of Tina and they are talking to each other and the interesting thing is that they lost their memories and don't know who the other person is. The story is cool and much better than in the first one.
Gameplay:
The gameplay is also much better. Unlike the first Super Adventure Island the gameplay is more like Zelda now. You've got a big world (posted screenshot) you can discover by a float and of course there are different dungeons you have to get in and defeat a boss to progress through the game.Unfortunately the maps of the dungeons are not very good. Just like Zelda you've also got different weapons (different swords) and even different armors and shields and magic abilities (posted screenshot). There are also heart pieces and magic bottles to find to get more energy and magic. The difficulty is not as hard as in its predecessor but ok. The bosses are not to hard most of the time and the normal enemies are easy. The world is big and there are many things to discover and like in Zelda or Metroid you just can get certain items when you have a certain weapon or ability. That means you must/ can go back to old dungeons later in the game to find everything the game has to offer.
Graphic/Dungeons:
When you're on the world map the game is pixelated but when you're in the dungeons Master Higgins and the enemies are very well animated. The backgrounds are very varied and look different in each dungeon and they look very good. You've got some beautiful backgrounds (posted screenshots).
Sound:
The sound in the first game took a while to get good and here the sound is good from the very beginning. There are some nice funny tunes which match very well to the dungeons.
Conclusion:
Super Adventure Island 2 is more like Zelda with many items, things to collect, a big world and dungeons. It has a very good graphic with great colourful dungeons. It's not as good as Zelda but in the end a good adventure you will definitely not regret playing.

That game isn't too bad looking, so I might check it out one of these days. Good review btw. Nice and wordy. Good job.
