Tighter and twistier

After trying out the Caves and Cliffs in experimental mode, I feel like the caves should be more cave-like especially at around and under Y:0 because the caves are way too open with every ore exposed as if we're on a mountain instead of a cave. The caves needs to be a more closed up like they originally are before without the caves and cliffs changes. But of course add in the caves and cliffs update, but just make the caves more tighter and twistier because I don't like how open the caves are with every single ore exposed without being able to make so much of an exploration.
