Fun Fact: The Adventure Island games were quirky. For instance, one of the power-ups for Master Higgins is a skateboard and helmet. For a caveman.

The Adventure Island games were side-scrollers in the vein of the Super Mario Brothers games. Players controlled a caveman named Master Higgins who, surprise, surprise, had to rescue his girlfriend from a villain!

Master Higgins could mount dinosaurs which helped him traverse the levels and attack enemies. This sequel added underwater levels and vertically-scrolling levels, and introduced an inventory system which allowed the player to choose which dinosaurs to “equip.”

Adventure Island II was more difficult than the preceding title in the series: checkpoints were moved, and dying meant you started the level over from the beginning.
