I AM GROWT

Kill the exploding squirrels while growing your tree and keeping them away from the nest. Move the camera up or down using the scroll wheel or dragging with the right mouse button. Use the mouse to grow roots, branches, "tree houses" and even the tree itself(which is what you are supposed to do, because thats your score). Growing costs energy which you get every few seconds the more roots you have. Squirrels may or may not explode, but if they do they can destroy nearby "tree houses".
