The story of the game is that Deangelo (the player), a soldier, has a plane crash. He finds a cave that has magic water drops and if you (as Deanglo - the player) get enough water drops you get immortality. The cave is protected by the Water Monster and chases you through the cave.
You will have to jump, climb, and slide past various obstacles along the path - whatever the cave throws at you. You also get a bunch of POWER UPs!
