Money and Walls
Most of us are always stuck with tons of money, well this can change. You can use them up on upgrading defenses (cannons, Archer towers etc.), but they wont help, cause if they get to the defenses, they will destroy the easily. In my opinion you should waste you money on walls. This will make your enemies slower and they wont be able to get to the defenses quickly, giving a chance for the defenses to destroy them. In attacks walls are very dangerous, cause whilst you are struggling with a wall, your enemy will make most of your army die out and even if someone lives he will die when he gets closer to the defenses. This here, though is to tell you how to spend your money, well here you are WALLS WALLS WALLS!!!!
