About this Mod
What is No Block Left Behind?
No Block Left Behind adds over 100 new blocks to Minecraft, that fill in the gaps in Minecraft's building blocks. From chiseled calcite to red terracotta walls, it adds a new array of things for you to build with. It fits in seamlessly with Minecraft's creative menu. No extra creative tabs here. It's like it was a real block all along. This mod is still in beta so there's way more to come. If you have suggestions post them on the GitHub page.
