one other option would be to partner up with someone else for music. did you see this post? Composer looking for a team! - FrenJam 2: Electric Boogaloo community - itch.io
you could also try messing around and pencilling in notes in Fruity Loops if you haven't already. you might find it's easier than you thought, but i guess not everyone has a musical ear. Fruity Loops is $99 past the trial, but if you just wanted to make chiptunes you could try free software like pxtone.
