Copper and Caverns

The Minimum Viable Product.

• World is only 1 biome (a plains biome that is modified to spawn oak and cherry trees). Terrain is heavily simplified.
• Stone tools are replaced with copper tools, slightly elongating the progression and requiring you to hold onto wooden tools for a bit longer.
• Beneath the surface is a thin crust with copper ore. Beneath that is a large, dangerous cavern with iron, diamonds, and other valuables.
