Undo button

Can you bring the undo button back? Sometimes you just click the wrong spot or the wrong unit and it can ruin your battle when its a tough one... At least maybe not 5 but just one so we dont have to use that mistakes were made button so often! It is frustrating to lose a whole game because you clicked on something too fast.. Anyway, the game is nice! Well done
