In this boardgame for 4 players, you take a role of a critter - the Güs, whose goal is to collect precise combination of healing crystals and use their power to heal the forest creatures. You collect crystals from different parts of the magical forest and use the powers of other helpers who trade you crystal, double it, or give you the one you need to complete the recipe. There are also creatures in the forest trying to thwart your effort by blocking the specific part of the forest, stopping for short time, or destroying a crystal in your collection. The player who heals the most forest creatures wins the game.
