According to the game description, you are stranded on some island, off the coast of Africa. That makes it vry hard to survive.

Supposedly this remote island, has all sorts of fauna, lions, hippos, elephants (!), boars, crocs, hell, throw in a few chupacabras for good measure..

Run around killing these beasts and bring ruin upon this fragile habitat. Do not forget to harvest the ivory and skins. That'll learn 'em.
