Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

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.

If you'd like to make a video or content using this pack, go for it! If you do so, you must provide credit to me (Ambiguous Chameleon) and provide a link to this pack in the description and/or comments. Thank you!
