About this project
What does YellowMaze add?
Yellow Maze is a Fabric mod for Minecraft 1.21.4 that adds a mysterious new dimension, a massive boss, and a tense sanity mechanic.
Features
🟡 The Yellow Maze Dimension
Craft and place a Locker, right-click it, and get teleported into an endless dimension built entirely as a yellow maze of concrete and terracotta, lit by glowing froglights. Right-click a Locker inside the maze to return home.
💀 The Brain Boss
A towering red skeletal beast standing ~12 blocks tall, with a bone-white skull, glowing green eyes, horns, and a snapping jaw. It has 500 health and its own boss health bar at the top of your screen.
🧠 Summoning Ritual
Place a Plate (a runed altar), set a Brain Block on top of it, and the Brain Boss is summoned in a burst of soul fire and smoke.
📉 The Sanity Meter
When the boss strikes you, a sanity meter begins draining on your screen. Let it hit zero and you die. Drink milk to cleanse the curse before it's too late.
👑 Tame & Ride
Right-click the boss while holding 5 Brain Blocks (consumed) to make it yours. A tamed boss won't attack you, defends you by striking back at whoever hurts you, moves faster, and can carry up to 10 players at once. Use /bossallow <player> to grant others riding access.
