Theralite is a turn-based Roguelike game set on a distant planet, where players navigate through deep crystal mines filled with dangers and treasures. The gameplay emphasizes strategic planning, allowing players to take their time as the world only reacts to their actions. Players must mine for gems, explore their surroundings, trade, and battle various monsters while searching for a way to escape. The animated steps add a dynamic element to the traditional turn-based format, enhancing the overall experience.

As players delve deeper into the caverns, they will encounter level tiles that can be mined, yielding different forms of loot and treasure. However, players must be cautious, as mining can attract hostile creatures. Scavenging for resources is essential for survival, and players need to devise strategies to navigate the challenges posed by the environment and enemies.
