How to play Inca II: Nations of Immortality on Mac

Inca II: Nations of Immortality is the sequel to Inca, the surreal space combat/adventure game with a fantasy take on Incan mythologies. You start the game as Atahualpa, El Dorado's spunky and arrogant kid, who after taking the family starship for a spin gets himself into trouble when checking out a strange asteroid that has emerged. Eventually you'll blow it as things take a turn for the worse, and you'll have to return to your role as El Dorado, and save your kid as well as stop your arch-enemy, Aguirre who somehow has plans for the use of this mysterious asteroid. Gameplay consists of space combat in the "Tumi" a yellow wedge-like starship using pre-rendered bitmaps to depict graphics, with puzzle-solving sequences in between as well as digitized video cutscenes used to tell the story.
