Backrooms Building Blocks adds a collection of Level 0 inspired building blocks for Minecraft. This mod includes yellow wallpaper, ceiling tiles, fluorescent lights, and other decorative blocks designed to recreate the iconic Backrooms atmosphere. Built for builders, map makers, and Backrooms fans who want to create immersive and authentic environments in their worlds. Compatible with NeoForge 1.21.1.
Current version: alpha 0.0.1
This is an early alpha release. Features, textures, and block designs may change in future updates as the mod continues to develop. More Backrooms-themed blocks and content are planned for upcoming versions.
Note: This is my first Minecraft mod, so some textures, models, or features may be rough or unfinished. Feedback and suggestions are always welcome and will help improve future updates.
