Minecraft, But Every Block Spreads Like Sculk
Information
A Fabric 1.21.4 mod built by Steampwred for YouTuber Frosty.
This mod makes any placed block spread and clone itself like sculk. Breaking one clone normally removes all connected copies, but sneak-breaking preserves them. If left unchecked, the spreading blocks can eventually overtake your world.
Good luck beating the game...
Inspired by Skippy T & Element X.
Overview
Place a block and it starts to spread like a sculk catalyst.
From there, it spreads outwards onto other nearby blocks.
Break the original block and the spread withdraws, replacing itself with air.
Crouch while breaking the original block to stop the spread, leaving all blocks affected.
Most features can be toggled through commands.
