TOWERS

The bandits have to go through all your tower in order to destroy and successfully steal your village's treasure. Though, your job is to build your own tower to defense the bandits.
Each tower has six upgrade levels; the higher the level, the stronger the warriors and the more coin you can take from your enemies.
