It looks like your Lovers don't behave exactly like the ones in Dragonsweeper! (I expected them to be placed symmetrically horizontal on the board)
Are they not the same? O_o They face each other in a horizontal row. There may be more than 1 pair of lovers in the map in higher levels, though!
edit: omg I never noticed but they are equidistant from the edge! woah DragonSweeper keeps revealing more to me hahaha. I wonder if I should change mine to match or if the flexibility adds another element of "search" for the pair
