Moats and bridges could be a nice addition to the game. A moat can be used similarly to a wall. Players surround their base with a moat and a bridge. To get past the moat a player must knock down the bridge or train a boat for a small elixer price.
Prices:
Moat Per Block:500 coins.
You have to buy the bridge with it so that will cost 20000 gold.
Boat training costs 500 elixer.
