The entire world is procedurally generated using noise textures and compute shaders. I used a built-in noise library from Godot and wrote custom compute shaders to refine the texture as needed. I then used these textures to determine which tiles should be empty, and which should be stone ore some type of ore.
I created a custom tile-based lighting system for this game which turned out great. Certain tiles are light sources, and this light propagates to adjacent tiles, becoming dimmer the farther it moves. This system also accounts for daylight when outside the caves, and smoothly transitions to the placed light sources when night falls.
