Touch your screen to move your fleet. Press "boost" button to give your fleet a boost for 3 seconds. Gather resources and press "buy ship" button to get a new ship when you have enough resources. Use boost to catch-up to smaller fleets or to get away from bigger ones.
Try to keep your fleet together as you attack. It might be a good idea to take out enemy ships one by one.
