Very catchy overall, cute, and creative melodies
the first problem is the overall distortion, I know the fact that this is a video game genre, where the instruments are bit-crushed and sidechain isn't widely used. SO, you need to be careful, as there is no sidechain, you need to lower the volume of the drums, else it'd crash with the others.
Oh and this is for an fnf mod so I highly recommend having the vocals louder than the instrumental.
