The Mycelarium forest, hedgehogs and the Repeller

Above ground, Mycelarium shows a calm pixel-art forest that is alive but not hostile. Leaves fall and decay into food, hedgehogs wander across the surface, and trees can become future nutrient sources. Demo 2.0 added a Repeller mushroom to deal with the hedgehog.
