This took me a good bit to finish, in part because the terrain generation was so brutal. Not being able to select which tiles you're drawing resources from is a real killer. I think the loop idea is very solid and the resource management concept is definitely worth pursuing. I had a good time and the atmosphere was really striking. IT's a neat combination of Dwarf Fortress and a tower defense, though I feel it being less random and more challenging vis a vis the enemies it would have been stronger.
When I won, the 1,000 year jump button also did not work.
