The game starts outside the entrance to a cave. Your objective is to explore the cave system, find the hidden pirate's treasure and return it to your start location. But beware, the pirate is not likely to allow you to steal his treasure that easily.
Notes
This looks and plays like an illustrated text adventure, but there is no keyboard input. All you have to do is wander around using the joystick. Nevertheless, it's quite a challenge to map and there are still inbuilt puzzles or obstacles to overcome.
