I can understand the complexities, but I also agree that an Android port would be great. This is a game that lends itself to be played on a phone or a tablet, safely tucked under blankets in bed, during long winter nights.
Also, the android market might be very profitable. It reaches *a lot* of people.
But I would suggest to either upload both versions (the demo and the full one), or allow for in-app purchase of the full version, once the demo is completed.
In any case, great work. I love the writing, the worldbuilding and the aesthetics of the game.
