Adventure Island was released in the US in 1988. It is side scrolling game similar to Super Mario Bros. The premise of the game is that Master Higgins is out to rescue his mate from monsters.
As in any game there are powerups. the powerups are contained in eggs and contain shooting power, superior shooting power, faeries and a skateboard. Faeries make Higgins invulnerable. Higgins could be killed by enemies, fire and falling into pits.
The game is quite challenging as there are swarms of enemies and a lot of obstacles to face. Higins could be killed by one hit so you have to evade a lot. The other factor that makes it challenging is that the energy meter keeps on going down if there is no food intake. You could get killed because of that too. The game is fun however with engaging music and cartoony graphics.
