Run it
Copy the script and paste it into your executor.
-- Make sure you play any singular song before you run this script! Doesn't have to be fully; It simply doesn't set the UI in place yet.
_G.Framework = loadstring(game:HttpGet("https://raw.githubusercontent.com/Sezei/ff-kate-engine/rewrite/loader.lua",true))()Loads code from the internet. It downloads more code when it runs (loadstring + HttpGet), which can change after it was posted. From: raw.githubusercontent.com.
If you are looking for a cheat, this is NOT for you. Kate Engine is a QOL Funky Friday mod / modding framework allowing you to mod the game without adding any advantage to yourself during multiplayer based on which song you play and adds additional Quality of Life features such as an interactive healthbar, mania-styled combo counter, a better song progress bar, modcharts, and more; all customizable within a click of a button. The script is fully open source (I got nothing to hide!) and is open for contributions from players and developers alike.
