Copper and Caverns

• Stone tools are replaced with copper tools, slowing down early-game progression and requiring you to hold onto wooden tools for a bit longer. This also means "stone" (now copper) and iron have been pushed further underground, making them more of a challenge to get and making each tool stage more rewarding.

• Beneath the surface is a thin crust of vanilla underground generation with coal and copper ore. Beneath that is a large, dangerous cavern with iron, diamonds, and other valuables.

• Cherry trees spawn in forest biomes.

I made this mod because 1) I don't like stripmining and 2) I don't like how in the first 5 minutes of the game, you can immediately jump right from wood to stone to iron tools without even going underground.
