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. 🔧

  • 🧩 Required Library: Provides the shared foundation needed by many @heyitsfuzs mods.
  • 🔄 Multi-Loader Support: Helps supported mods work consistently across Fabric and NeoForge.
  • 🛠️ Shared Mod Systems: Supports common features used by dependent mods, such as configuration, networking, events, and registration support.
  • 🚀 Lightweight Foundation: Runs in the background without adding gameplay content or cluttering your world.
  • 📦 Improved Modpack Reliability: Reduces duplicated systems between mods, helping dependent mods behave more consistently.
  • 🌐 Client and Server Support: Designed for use in single-player, multiplayer, and dedicated server environments.
