Some theme!
I was amazed at how much of an original theme you were able to turn this into! It was especially fun because I got the feeling of a broken romance or some deep thing like that. While the title certainly helped in giving me that idea, what matters is that you convey such strong emotions with such simple music. I can tell it is 8-bit style, but still very well done. It certainly fits your description as it really jumped around in the beginning. It comes off as less aggressive as it goes giving a more casual style.
