SiZed: The Minecraft Size-Challenge
Play Minecraft like never before! With the SiZed challenge you grow every time you destroy a block or kill an entity. Very basic, but worth a try!
What it does
SiZed turns Minecraft into a challenge! You are shrunk/enlarged to a certain size and grow with every block you mine and every entity you kill. You can adjust many things: You can set whether you grow when you mine blocks or whether you kill entities. You can set the starting size and the size at which you grow or shrink. You can start or stop the game as often as you like. There is a help menu in which all commands are displayed and you can get help on our Discord server. Everything is kept quite simple. The command /sized controls everything. And the Pehkui mod does not need to be set up or used! Everything is managed by the SiZed Challenge via the Pehkui Mod.
Prerequisites
