- Slightly lower iron ore generation so it's harder to get.
- Add copper armor (replaces chainmail).
Pretty sure that's all I added...
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.
