KSnakeDuel

Snake Duel for KDE (KSnake) is a snake game in the KDEGames division of KDE 4. In KDE 4.x was called KSnakeRace.

Gameplay
The player controls a snake which eats apples, and when all the apples are eaten must exit the level first. The player’s snake dies if its head hits a wall, another snake, itself, or a ball.

There may be other snakes (their number is configurable and may be between 0 and 99) on the field. Those other snakes may have one of the three kinds of behaviour: Random, Eater, Killer.

There may also be balls (also configurable, 0-99) bouncing between the walls of the field, and killing the player’s snake when they hit it on the head. The behaviour is one of: Dumb, Average, Killer.

The appearance of the walls is configurable and may be a solid color or one of the predefined images.

Also selectable is the level to start with.
