Chapter 1 now takes place on an island. You can see the whole thing from the right spot: the coast, the forests and the mountains in the middle, with the sea around it.
The mountains took a few goes. The first ones were spiky and looked off, so the generator went through a few versions until they had broad, flat tops. Trees no longer grow on them.
New worlds also look for a good crash site now, one with trees, water you can fish and sand nearby, and Luna tells you where things are. Felled trees drop saplings, and saplings grow back.
The game also got a new look: heavier, darker block textures, new lighting and menus in a modern industrial style. And there are graphics presets now, so you don't have to tweak ten sliders yourself.
