Sigma Tower Defense by jhonata7 is a free RPG-flavored tower defense: the genre's tower-placement loop with role-playing progression — towers that level, presumably, and a sigma grindset for the minions. Two screenshots show the defense.
TD with character growth — the towers gain XP, the waves gain respect.
