It's similar to Super Mario Bros. (the seminal adventure video game). You go through 8 worlds with 4 levels per world, with a villain at the end of the 4th level. The 4th level is always a dark forest instead of a castle.

In this one, we follow Master Higgins in his difficult quest. This is an extremely hard game to beat. I've only made it to 8-3, though my brother once beat it by using the Game Genie (cheating?). That said, it is extremely fun. Hits will take away your power, which you can get back by eating fruit (see, it teaches good eating habits). Eggs (sometimes hidden) contain goodies, but be sure to avoid the ones containing an eggplant, which will drain your power (but it is possible to hurry and make it to the end and make 5000 extra points with it in some levels).

As indicated in the manual, you can find a hidden bee at the end of 1-1 and be able to resume the game from where you left off by a simple combination of the buttons when you run out of lives. It would be impossible to make it past the first couple worlds without that.

It was followed by a similar, but much easier, Adventure Island II. Adventure Island for the Game Boy was actually just Adventure Island II (not this game) rebranded.
