What started as a ruthless quest for maximum FPS became something far more dangerous. By stripping Minecraft’s worldgen down to its bare essentials, we removed every non‑critical computation and storage system… and in doing so, we removed the safety nets that kept the Overworld sane.

Now the landscape itself is out to get you.

Features:

 

      1. Extreme Performance – Stripped‑down logic for maximum FPS.

      2. Worldgen – Terrain that feels alive… and slightly hostile.

      3. RNG experience – Sudden pits, cages, and spike‑lined drops.

      4. Killed by the Views – Landscapes so stunning they could be lethal.

  1.  

NOTE: Although I tried to make this less deadly, it is based on KillerWorld.
