Isaac's FNF Engine

Hello! Welcome to my rhythm game engine! I have frequently been wanting to make a mod for FNF, but I didn't want to go through the hassle of learning how to make a mod for the game. So, instead I built an entire engine based off of the game. (As you can tell, I am not very good at managing my time.) Anyways, I kinda just wanted to make some FNF songs, so now I have # way to I guess. I hope you enjoy it!
