Sorry, questions! We don't have Descartes Cove, so I can't be of any help. But I have downloaded the demo and the game looks wonderful. So if you find your answer, could you report back about what you think of the game? The level of challenge that it provides, verses the cost of the game? I would love to hear from you, or others, who have tried it!!

Hopefully, someone else will chime in with the answer...
