   For start game, i use this code:
   if(game){
   //New Start Game
   [game release];
   }
   game = [GameScene node];
   [game retain];
   [[Director sharedDirector] pushScene:game];

   When starting a new game, variable game not nil, then called [game release]. And in window Organizer->Console print:

   Mon Sep 14 22:34:06 unknown configd[21] <Notice>: kernel memory event (90), free: 373, active: 1787, inactive: 945, purgeable: 0, wired: 11148
   Mon Sep 14 22:34:07 unknown SpringBoard[22] <Warning>: Memory level is urgent (10%). Asking 'OceanMonster' to quit.
   Mon Sep 14 22:34:07 unknown SpringBoard[22] <Warning>: Writing low memory report regarding 'OceanMonster'
   Mon Sep 14 22:34:07 unknown configd[21] <Notice>: kernel memory event (95), free: 256, active: 910, inactive: 544, purgeable: 0, wired: 11183

   It turns out the function [game release] does not release memory.
   Class GameScene.m have funstion dealloc:
   - (void) dealloc
   {
   [super dealloc];
   }
   How start new game???

   A couple of tips:

   if(game){
   //New Start Game
   [game release];
   }

   The if check is not necessary, you can send messages to nil objects and nothing will happen. That being said, you shouldn't really need to retain or release your Game instance.

   [[Director sharedDirector] pushScene:[GameScene node]] will retain the GameScene instance and release when it is done with it. If this is the first scene you are running you will need to use runWithScene instead of pushScene.

   So at a later time you can start a new game with:

   [[Director sharedDirector] replaceScene:[GameScene node]]; This will release the original GameScene instance.

   make sure where you define game
   GameScene * game = nil;

   also I see a pushScene, but do you popScene when you are done?

   if(game){
     [game release];
     [[Director sharedDirector] popScene];
   }

   I make Pause game:
   [[Director sharedDirector] popScene];
   After Start New Game:
   if(game){
   //New Start Game
   [game release];
   }
   game = [GameScene node];
   [game retain];
   [[Director sharedDirector] pushScene:game];

   I save variable game, bacause i can Resume game:
   -(void)resumeGame: (id)sender {
   [[Director sharedDirector] pushScene:game];
   }

   GameScene a second scene, MenuScene is first.
