You are a monarch and your goal is to prosper and enlarge your kingdom, while protecting your equipment, your workers and especially your crown! During each day, you can browse the environments - from right to left - to recruit your troops, order constructions or even collect your gold. During each night, you will face hordes of enemies - the Greedlings -, who will appear on each side of the map and try to destroy your walls and steal your crown. Kingdom's gameplay is mainly centered on money management, necessary for any type of action that the player will want to implement. For example: recruiting new people, being able to equip them, building and improving structures, or even unlocking new levels.
