Mama Mu och Kråkan

Description from the designer:

Mama Mu is a lively cow who wants to build a treehouse. She asks her friend crow to help her. Crow, as always, is reluctant, but she does. She helps Mama Mu with collecting all the wood needed for the treehouse and a ladder to get in.
Aim of the game is to build your ladder, and when you are done you can let Mama Mu get into her new house.
of course you have to take care, wood can get stolen and the farmer should not catch the cow and the crow do "human" things.
based on a childrens book by Jujja Wieslander and Sven Nordqvist who also were the artists for this game.
