Super Adventure Island 2 on SNES is an amazing game. Handling, graphics and level design are successful, without being perfect of course. When I played this game, I rarely felt a sense of boredom (except the sadness that is Curly's Casino).
It is a very particular opus of the series. This game is closer to the gameplay of Zelda 2 (There are equipment, magic, puzzles ...).
The soundtrack is excellent, very sentimental in my opinion. My favorite music are Aquatic Assault, Hiya-Hiya Island, Boss Theme 2, Fuwa-Fuwa Island, Heart of Darkness and Fair Tina.
One of my favorite Super Nintendo titles, unfortunately too little known.
Rating for the game and the soundtrack : 85%
