Friday Night Funkin' vs Cube (Canceled)

This is my first own fnf mod, it is not finished yet, work is still in progress.
This mod I am not going to do with one week, I plan to make a whole plot, I am not sure that I can make such a huge mod, but I will try.
The mod will be in the style of Geometry Dash and that very popular game, and what is the plot of the mod?
After the battle of Whitty, Tricky, Agoti and Tabi, Boyfriend and Girlfriend will need a letter that brother Cube invites you to a rap battle in their universe of Geometry Dash and Girlfriend teleparts us to that place and we meet Cube Boyfriend and Girlfriend decide to fight a battle with him and the rep begins.
