🌟 Key Features

💾 True Saves


As you travel the world, you will find Save Points across various structures (Villages, Pillager Outposts, Ancient Cities, Woodland Mansions, Strongholds, and many more). Interacting with them fully restores your health and opens the classic save interface. But be careful: saving acts as a full time backup. If you die, the world will roll back to that exact moment! Your resources, destroyed blocks, killed mobs, and even raid progress - everything will revert to the state it was in at the time

💬 Unique Texts and Atmosphere

 

A unique save text is written for every biome and structure, conveying the atmosphere of the surroundings and filling you with Determination. Experience the familiar design, sounds, and fonts that will make you feel like you are in a completely different game.

🔪 Genocide System


Your actions have consequences. The mod tracks how you interact with the world. If you ruthlessly and purposefully exterminate a specific type of creature, their population will run dry. Available progression paths: Neutral and Genocide.

⚠️ Important Note


Since the mod physically "rolls back" the world and time when a save is loaded, it is intended strictly for Singleplayer, and it is highly not recommended for use in modpacks.
