Even from the aerial picture of Dunkerque, most of the holes there look like they would appear and play like fairly normal golf holes from ground level. It doesn't strike me as all that out of line with the course that keep a cluster of bunkers in a shape that suggests a bear's paw, or a letter, or have tees in the shapes of card suits. It's a little gimmicky, but it adds visual interest without bothering the golf, really.
