Hmm, I get what your trying to go for, One thing i'd say is that you should try to fill up more frequencies (By that i mean have your instruments sit at different octaves) since the
drums kinda muddy the guitar.

I don't know what FnaF music is supposed to sound like, so I don't know how to really review this. But as an actual piece of music it sounds really over compressed, there's really no mixing and the dynamics are way off. It's not hard to listen to by any means, but it could have certainly used a few more passes.
