Puzzles Lib is a library mod required by many of @heyitsfuzs Minecraft mods. It does not add new blocks, items, mobs, or gameplay on its own; instead, it provides the shared systems those mods need to run properly. 🧩
For players, this means simpler installation and more consistent behaviour across supported mods. If another mod lists this mod as required, install it alongside that mod and leave it enabled. ✅
The mod is built mainly for @heyitsfuzs own projects and is not intended as a general-purpose library for other mod developers. Its focus is keeping those mods reliable, maintainable, and available across supported mod loaders. 🔧
