Sweetheart was my favorite boss fight, and had such an amazing theme, reason to why I decided to extend this track.
I didn't record footage of this boss fight for the background video, so I used a screenshot I took.
Hope this isn't a problem compared to what my usual 'extended version' videos use to be.
