Due to a disaster you need to annihilate the population of the world. The basic rules are those of the medieval time: Knight beats Beast, Beast eats Damsel, and Damsel charms Knight. The game features anti-aliased graphics with highlighting and a morphing interface. There are full undo/redo and several gameplay modes of progressive brain-teasing in the game. A filter-based map generator is implemented, with a nearly infinite number of twisted maps.
