Quite nice!
I'm not sure this is correct for the super challenge as things like the drums would certainly sound different when the song plays in reverse but the text is also messed up on the option so IDK if it was intentional.
from listening to it I think you were probably going for the hard challenge where the notes are the same forewords and backwards.
Overall I liked it though It might be a tad simplistic since most notes happened on the beats and there was little syncopation to bring more depth to the song.
