Island Siege

Take every island on the board. Lose your castle and it is over. Click or tap an island, then a linked one, and it sends every troop it has. Each island moves once per turn, and an island that receives troops is spent too, so you cannot relay across the map. Hit one target from two islands in the same turn: soften it with the first, take it with the second. Towns give resources - spend them on cities, walls and pastures. Click End Turn when your moves are done.
