skyverworld

Everyone has, at some point in their time playing Minecraft, “Wow! I sure wish that the Overworld was frustrating and dangerous to navigate!” No? Nobody has thought that, ever?

Skyverworld is, as the name implies, a world generation datapack that changes the overworld into a series of chaotic sky islands. Unless you have a quite unlucky spawn, it is beatable in survival mode; strongholds generate as normal, and you can get to the Nether just fine.
