Floating
Adds a completely new world type to Minecraft that completely changes the familiar landscape. Instead of the standard surface, you'll get an exciting universe of floating islands created based on all the biomes of the regular world.
A feature of the mod is that when Biomes O' Plenty is installed, an additional world variation automatically appears, using the extended set of biomes from this mod.
In the singleplayer game creation menu, you'll find two new options: "Floating" for standard biomes and "Floating (Biomes O' Plenty)" for extended landscape diversity.
