Gemstone Keeper is a twin-stick shooter where avid explorers go down into the Cistershire Caverns, a large, dangerous and mysterious set of caves and caverns that are filled with vast amounts of rare and valuable gemstones. The deeper explorers go into the caverns, the more precious and high-quality gems can be found but at the risk of encountering more dangerous creatures that live amongst them. Only those who return to the top can earn what they keep, so those who perish will lose what they get.
