Questions in My Little Pony

Someone is interesting in creating FNF mod about Elements of Insanity, I talk about the Elements of Insanity from TheInvertedShadow, because this universe is dead, no one create the content in video gaming in our days, so someone have idea make FNF mod?

So, I'm thinking of developing my own fan game, though I'm kind of stuck in a rut as to how I can incorporate the characters' abilities. I'm going to be using GameMaker as the engine. That said, any suggestions?
