Overview
This pack must be installed during new world creation! It can't be used on pre-existing worlds.
This is a superflat challenge where at the start of every day, the entire floor changes to a different block. All 3 dimensions have been converted into superflat terrain and are each affected by the floor change. Each dimension contains the structures/mobs needed to beat the game.
