Ah yes I did indeed forget to add music to the cutscene. I couldn't find anything that I liked so I just decided to leave it silent.
Unfortunately, I didn't have time for an end cut scene but the idea I had was pretty cool, after completing all the levels, the player would reappear behind the boss of the cutscene and just go Psyche I tricked you and then in a grandiose way explain that the robots he used were actually bombs that would explode in his command. The player would then leave, walk-in slomo, put her glasses on and an epic YEAH would play as the villain's lair gets blown to smithereens!
On another note, THANKS FOR PLAYING MY GAME!!
