# Gemstone Keeper

Summer DB entity ID: 03447189\-0366\-4ca9\-8457\-6c79c9b5f1d7

Steam App ID: 522080

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\. This game combines the quick and reactionary feel of a shooter with the exploration and decision making of classic roguelikes\.    Using an ASCII art aesthetic in its purest form, all visual assets are produced from a single text font file, software rendering and visual effects\. The weapon and bullet system is fully interchangeable, over 150 gemstones to collect, several creatures and bosses, different game modes and a soundtrack that echoes through the open spaces in\-between the rocky walls\. Gemstone Keeper is the shooter that is both fun and eerie\.
