The Audio is the track "Back In The Saddle" from the AAA Epic Stock Media Clips Retro 16bit. I do not remember if I got that from a Humble Bundle Pack or Fanatical but came with a lot.
I went a little nuts on hard mode with spikes. Think that along with particle effects and moving objects from other 2 zones lagged it bad causing hard mode to be harder than intended. Ill keep that in mind for next time to not do.
