Polar Defense

Play as a territorial, baby, genius, polar bear trying to stop the construction of a highway spanning from the forests of central Europe all the way to the heart of the north pole. She must stop cars and all manner of road-building vehicles by building environmentally friendly defense towers, like solar powered laser towers, wind-powered spinning blade towers etc., that turn the vehicles into scraps that she can then use to build even more towers to protect the environment and her home base. She also needs to worry about fishing in a sustainable way to keep herself alive.
