Very cute faction! I would definitely not want to attack those spiky hedgehogs. Then again, I'm not sure if I want a bear whacking me either!
I am curious how you've found the generation of blackberry tokens. It makes thematic sense that they grow where other blackberries are, but if the bear had a sudden surge of hunger and was able to gobble up multiple clearings in between your turns, does it become difficult to get grew new berries?
