Making a Game Part 3

I'm done.. I'm done... I'm done! I can't believe I've finished my first serious goal for a project. At some point I want to add different difficulty levels and fix it so there's an "introduction" light sequence. For now, I'm going to leave it. Code is after the break. I added comments so that you may understand it. if you have any questions feel free to email me.

int count=0;
int currentOn=7;                           //currentOn variable is the current LED position.
void setup()
{
 /* introSeq2();   //Couldn't successfully setup the loop so everytime the game was over the intro would start again.
  introSeq2();     //Chose to comment out the intro.
  introSeq();
  count=0;
  introSeq();
  count=0;
  introSeq();
  count=0;*/
  Serial.begin(9600);
  digitalWrite(currentOn,HIGH);
}

void loop() {
 leftright();
 if (currentOn>=12 || currentOn<=2){
   Serial.println(count);  
   gameOverFlash();
   gameOverFlash();
   gameOverFlash();
   delay(1000);
   asm volatile ("  jmp 0");
 }
}

//(***************Break up for first IntroSeq ********************************************

    for (int i=2; i<12; i++){
