You have knights wandering around the map. Monsters emerge from caves, looking for villages to smash. Knights will fight any monster they run across until one of them dies.

You can click on a knight to call him to the castle, which is technically a definition of Summoning. If a knight is in the castle, you can choose exactly where to send him, and after he arrives, he'll automatically go to the nearest village. If a knight is injured, he'll rest in a village until healed. New knights slowly spawn over time. The goal is to defend the villages for as long as possible.

My motivation to work on this is currently very low. I'll just fix up a couple of major bugs, throw in a main menu, lose condition, and points, and call it a game.
