An incremental mining game with fully destructible caves. Every pickaxe strike removes an actual piece of rock. Mine ores, sell them, and buy upgrades. Upgrades are not just +10% damage. Equipment and Curses change how you mine, move and explore. Combine them to create your own build.
What a Steam playtest is
A playtest is a test build of a game that developers offer before release. On Steam you sign up for testing on the game's page. Whether you get access immediately, or the developer invites you first, is decided by the developer and can change.
