First, the game's interface is fairly minimal. To get information on your buildings is a simple matter of hovering your mouse over them, and clicking a building selects it for further modification. When this is done, a previously empty selection interface displays on the left side of the screen with various icons to choose from.

Navigating the space, a small island upon which the various ally and enemy buildings stand, requires careful use of the mouse. There is a directional compass in the lower-right corner, with arrows indicating the different directions in which the camera view can travel. Alternatively, placing the cursor at the very edge of the right and left peripheries of the screen will rotate the view laterally around some central point; this point does not seem to be defineable. Similarly, placing the cursor at the top and bottom peripheries will rotate between a directly overhead view and a nearly ground-level view. Doing things this way will likely be easier to handle when in the thick of combat, but unless you're playing the game in fullscreen mode, it's difficult to land the cursor just right. Also, what this game could really use is a flat pan navigational move, as the constant rotation gets to be a little irritating.

The object of each level is to take out the enemy. This is done mainly by sending units to attack enemy buildings. There is no direct control over your units, there is only the order to attack. There are two basic units under your command: peasants and knights. Knights are generated in castles, and peasants are generated in villages. You're given a single castle to begin each level. Hovering the mouse over the castle will show the unit strength within the building. With the castle selected, right-clicking on an enemy building will cause the units in your building to stream out and attack the target building. If the number of your troops outnumbers the number of enemy troops in the target building, your units will inhabit the newly-conquered building. At this point, the building and its unit-generating functions belong to you. If you don't attack with enough troops, you will destroy enemy units, but your troops are lost afterward.

The peasants that maintain the villages can also be used to attack buildings, but at their default level they're much weaker than soldiers. They mostly contribute to the generation of one of the two main resources in KM, food. The other resource, gold, is generated at mines. To capture a castle, village, or mine is the same tactic: overwhelm the enemy with superior forces.
