To provide users with NEI-like light overlay.
This mod requires Forge or Fabric. (Fabric API is required for Fabric)
This is a client sided mod.
Press F7 to toggle the light overlay, configurable through Controls Settings.
A yellow cross means that mobs can spawn at night, a red cross means that mobs can spawn anytime.
