Making a Game Part 2

Made some progress with the game. Thought I was almost done with the coding but I'm stuck and will seek help with it. Current progress is after the break. Decided to start commenting my coding as well so I don't forget everything if I try to look at something later.

int count=0;
int currentOn=7;                           //currentOn variable is the current LED position.
void setup()
{
 /* introSeq2();
  introSeq2();
  introSeq();
  count=0;
  introSeq();
  count=0;
  introSeq();
  count=0;*/
  Serial.begin(9600);
  digitalWrite(currentOn,HIGH);
}

void loop() {
 leftright();
}

//(***************Break up for first IntroSeq ********************************************
void introSeq2(){
    for (int i=2; i<12; i++){
  digitalWrite(i,HIGH);
  delay(100);
  digitalWrite(i,LOW);}
}
//(***************Break up for Second IntroSeq ********************************************
void introSeq(){
  for(int j=6; j>1; j--){
  digitalWrite(j,HIGH);
  digitalWrite(j+1+count,HIGH);
  delay(200);
  digitalWrite(j,LOW);
  digitalWrite(j+1+count,LOW);
  count += + 2;}}
// ****************Break up for Move Left *********************************
int leftright(){
  int right = analogRead(0);           //Read value from joystick right
  int left = analogRead(1);            //or left.
  Serial.println(right);
  Serial.println(left);
  delay(500);                          //Large delay for testing purposes.
  if (right == 0)
  {
    digitalWrite(currentOn,LOW);       //The current LED is turned off
    currentOn-=1;                      //the position is decreased by one
    digitalWrite(currentOn,HIGH);      //and the new current LED is set to high.
    while(currentOn <= 15)                
    {
      delay(300);
      digitalWrite(currentOn,LOW);
      currentOn+=1;
      digitalWrite(currentOn,HIGH);
    }
  }

  if (left == 0)                       //Same code as previous if statement except in the opposite direction.
  {
    digitalWrite(currentOn,LOW);      
    currentOn+=1;
    digitalWrite(currentOn,HIGH);
    while(currentOn >= 0)
    {
      delay(300);
      digitalWrite(currentOn,LOW);
      currentOn-=1;
      digitalWrite(currentOn,HIGH);
    }
  }
}
