Love is a popular topic for our culture. Romeo and Juliet remains one of the most popular works of literature hundreds of years after it was written. Movies about love and relationships are as common as a pigeon, bringing in millions of dollars whenever they’re released. Poets from as far back as the Ancient Greeks have mused on love. Love is commonly expressed through music. As Huey Lewis & the News sang, “make one man weep, make another man sing”. One of Pat Benetar’s greatest hits, Love is a Battlefield, remains a classic. But as it turns out, love is not a battlefield, but a puzzle game, and a damn hard one at that.
