Use arrow keys to navigate Mr Smiles. Press S to start. Once you get to the boss fight with Admiral Anger, hold down Q. If you have won, then Admiral Anger's health should be less than 0. (In negative numbers) Same for Mr Smiles. ENJOY! Song may glitch a little bit.
All credit goes to TheMasterGaming321 because they helped me so much. Also, thanks to InfectiousReindeer for the idea of Mr Smiles's looks.
