From the campaign:
In The Grimm Forest, you are a niece or nephew of one of the 3 Little Pigs of legendary fame, competing to build a set of three houses quickly out of Straw, Wood, or Brick. Players make secret plans to travel to parts of the Grimm Forest to gather limited amounts of resources that are available there.
The Game is played over multiple rounds, split between two main phases : Gather and Build.
During the Gather Phase, you will move to one of the Gather Locations; there you will gather resources to use in your house-building efforts.
The Kickstarter is doing well. They're already well over their funding goal. So it's on to stretch goals for the next 23 days.
