 or a friend. The aim of the game is to live longer than your opponent. To do
 that, avoid running into a wall, your own tail and that of your opponent.
 </para>
 
 <para>
 &ksnakeduel; is a simple Snake-like game. The aim is to survive as long as
 possible and eat as many fruits as you can.

 <para>
 Once a round is started, the players do not stop moving forward (unless the game
 is paused).  All you have to do is avoid crashing by changing your players
 direction. Additionally you can try to hinder your opponent.  For this it is
 possible to increase the velocity by pressing your accelerator key.
 </para>
 
 <para>
 A round starts when all human players press a direction key. The initial moving
 direction is then in this direction.
 </para>
 
 <para>
 If you want to interrupt playing, select the <menuchoice> <shortcut><keycombo
 action="simul"><keycap>P</keycap></keycombo></shortcut> <guimenu>Game</guimenu>
 <guimenuitem>Pause</guimenuitem></menuchoice> menu item.  Additionally the game
 is paused when the game loses the keyboard focus, &eg; when switching to an other window.
 </para>
 
 <para>
 To continue the game, select again this menu item or hit the keyboard shortcut.
 The game will also continue if you press one of the direction keys. But be
 careful, your player switches to this direction immediately.
 </para>
 
 
 <para>A game consists of several rounds, and ends if a player has at least
 nine points, and additionally two more points than the opponent. The current
 score is always displayed in the status bar.
 </para>
 
 <para>
 You can change the difficulty level of the game using the
 <menuchoice><guimenu>Settings</guimenu> <guisubmenu>Difficulty</guisubmenu></menuchoice>
 submenu or the drop-down box on the status bar. The difficulty influences
 the speed of the game and the computer player.
 </para>

 <sect1 id="computerplayer">
 <title>The Computer Player</title>
 
 <para>
 You can play against a computer. The difficulty level of the game influences the
 intelligence of the computer player.
 </para>
 <para>
 At low levels the computer doesn't care about the opponent and just moves
 around. At higher skill levels the computer tries to hinder the opponent when he
 comes near.
 </para>

 <sect1 id="using-keyboard">
 <title>Using the Keyboard</title>
 
 <para>

 accelerate.
 </para>
 
 <para>

 change
 the direction of your player.
 </para>
 
 <para>
 Acceleration only occurs while the acceleration key remains depressed.  When you
 release the acceleration key, velocity returns to normal.
