If you really wish to validate the name "Beachwars" i personally recommend making the beaches bigger, placing each temple on, or as close as possible to the beach head, and making the most readily available source of food, fish.
This will give the players on the map a reason to make war over said beaches! =D
Otherwise, i'd call it "The Turtle" cause thats kinda what it looks like to me, Top-down view.
