With its high points outweighing its low points, Primal Planet sets the platforming action in the harsh survival of a Stone Age populated by dinosaurs and invaded by alien ships. The mid-campaign, with its narrative emptiness and trivialization of some mechanics, gradually loses the emotional strength and gameplay dynamic of the beginning, which is compounded by the poorly functional mapping. However, those who enjoy facing dinosaurs and exploring the corners of dangerous, interconnected 2D worlds will have reason enough to venture into this prehistoric world.
