This mod completely changes how Minecraft worlds generate by randomizing nearly every block in the game. When a world is created, blocks are replaced with other random blocks, turning familiar terrain into something unpredictable and challenging.
To keep the game playable and progression intact, certain critical blocks are excluded from randomization. End Portal Frames and Spawners always generate normally, ensuring that strongholds, the End, and mob-based mechanics still function as intended.
