use the orange and black one in key locations to trap them around a couple of blues reds and greens
its kinda boring but if you play buy low and sell high make sure your houses are near each other so you can monitor them
start with raw resources first wood food and stone
buy something in the shop before you head out
you dont go to a shop often so buy when you can
keep the ice towers up and upgraded and they wont get far
interesting game i like playing games with little work when im at work
