In The King is Watching, you are tasked with running a kingdom, naturally, and defending it from relentless waves of intruders. Most of the gameplay unfolds on a grid located on the left side of the screen, divided into squared plots of land. These plots are where you are able to place various resources, buildings, fields, and more, in order to expand, further enhancing your chances of survival. Your main goal is to survive enough waves to take down an end area boss.
