Undholm

"Undholm is a single-player simulation game, currently in early access, inspired by Rimworld, Banished, and Dwarf Fortress. With a focus on player freedom, you can build and manage a dwarfish colony in many ways, such as creating a walled-off mining base, establishing a military camp, or specializing in cooking and trade. The goal is to provide a versatile and experimentation-friendly experience with various paths to success and adaptability in a changing world."
