How to Play Tangled Yarns

About Tangled Yarns, from BoardGameGeek:

Tangled Yarns is a thrilling 1-6 player cooperative board game where you and your friends step into the hooves of a brave flock of sheep uniting to save their world from a terrifying cosmic horror! In order to stop the Shepherd and win the game, players must move their sheep to corresponding hex tiles in the city and the close cosmic gates before he can pass through. Sounds simple enough. But the Shepherd has many servants to aid in his coming. Cultists will attempt to reach the sacrificial altar in the city center to summon him directly and wolves will be lurking in the shadowy city streets, hunting you… But the sheep have come prepared. Make use of arcane artifacts to rotate the walls of the city itself to block the paths of the cultists and utilize a unique combat system to fight off the wolves! -description from the publisher
