Can any one help me with menu's?

Can any one help me with menu's?
I'm totali new in Arduino world.
I build airsoft prop bomb so I need help with menu.
Button's will be connected trough single analog input and voltage divider!

Menu FlowChart is in the link...
Menu FlowChart

Thank You...

What you have done until now? What is your main problem? From the flowchart it seems to me to much work to ask to someone to do it for you for free. Don't you agree?

Of course it is much work so I dot mean that anyone will do all work for me...just need hints, or some sketch or an similar example...
P.S. sorry for my bad english :roll_eyes:

Maybe you can take a look to this. I never tried it so, I don't know if it works of if is easy to implement.

I made a menu…it’s not like i wanted but will be good…

void selectGame(){ //Menu
  lcd.clear();
  lcd.setCursor(0,0);
  int i=0;
  char* menu1[]={
    "Bomb Defuse", "Key Bomb Defuse", "Data Stolen", "Comp Infection"}; //add many as you want
  lcd.print(menu1[i]);
  while(1){
    if(BT_RIGHT == get_key() && i<3){
    tone(tonepin,2400,30);
    i++;
    lcd.clear();
    lcd.print(menu1[i]);
    delay(500);
    }
   
   if(BT_LEFT == get_key() && i>0){
    tone(tonepin,2400,30);
    i--;
    lcd.clear();
    lcd.print(menu1[i]);
    delay(500);   
   }  

   
 if(BT_SELECT == get_key()){
   tone(tonepin,2400,30);
   lcd.clear();
   switch (i){
     case 0:
     bombDefuse();
     break;
     case 1:
     keyBombDefuse();
     break;
     case 2:
     dataStolen();
     break;
     case 3:
     compInfection();
     break;

      }
    }
  }
}
