In this empire, we do not sleep. Grow and Conquer is an Active Strategy game. There is no button to play the game for you.
You, the Emperor, are present on the battlefield. You decide when to fire your skills. You decide when to summon reinforcements. If you are lazy, you will fall.
Your Hero is your avatar. You must drag and move him to position him for the best firing angles. Standing still makes you an easy target for enemy archers.
The difference between a victory and a defeat is often a single well-timed 'Arrow Volley' that wipes out a wave of goblins. Master your timing.
