The melee combo doesn't really help since the missles still damage you even though you are near? This game is pretty stupid, just keep throwing fireballs and run. Just keep doing that. Almost no strategy at all... Try having more attacks for you and the enemy, missiles should hit the ground randomly, not where you are. You are standing right next to the turtle, you see the missiles exit the top left of the screen, and they fall down on you...how does that work out?
