About Split Self
From ModrinthI remember everything; you did this to yourself.
Split Self
An Immersive Horror Minecraft Mod for Fabric 1.21.1
Trapped in the world you made, by the decisions you made, trying to claw their way out by any means necessary... you monster.
Split Self is an immersive horror Minecraft mod aimed towards an alternate version of yourself — one that was left behind by you. They will interact with your world, and other things, in ways they think will let them out of their created cage. They will break worlds, try to kill you, and personally speak to you. It doesn’t want to interact with your character. It wants to interact with you. So let them take control, let them take back the life you stole. After all, it was you who did this to them in the first place.
Your choices matter. Your actions have consequences. And now… they want out. This will only end once they are finally free.
All you need to let them do is take their life back.
