Diggy Diggy is an idle mining game where players take on the role of managing a team of dwarfs to excavate resources deep underground. The core gameplay loop involves directing dwarfs to dig, selling the materials they gather to earn gold, and then using that gold to level up the dwarfs, improve their tools, conduct research, and hire more dwarfs. Players can engage in various activities such as smelting raw materials into refined products, enriching rare ores, forging tools, building housing for their dwarfs, and managing automated tasks. The game features a comprehensive material system with numerous ores, ingots, and stones, each with its own price and stock value. Financial management is key, with options for investments and tracking income and expenses. The game also includes systems for enchanting tools and leveling up dwarf stats like dig power and wage. A welcome message guides new players through the initial steps, encouraging them to "watch the dwarfs start digging," "sell materials to earn money," and "level up your dwarfs." Players are also encouraged to provide feedback and bug reports through Codeberg Issues. The game collects anonymous statistics to help with balancing, with an option to opt-out in the settings. Screenshots are intended to showcase the game's interface and mechanics. The game's slogan is 'Dwarfs go down, Numbers go up!'.
