Isle of Arrows - Tower Defense

Starting with a path a few squares long, clearing waves of mobs earns gold to buy fresh pieces of track and new turrets that are randomly selected from a gradually expanding range. Many turrets come with a conjoined grid square of water, which makes placing them on the game’s minimal islands an additional challenge. Soon more paths appear on neighbouring islands, forcing you to split your resources to defend them all simultaneously, in this sophisticated and engaging take on a well-established genre.
