Hack-proof maze game?

I'm making V.2 of a maze game I made a while ago (http://soulabluerose.deviantart.com/...-V-1-101927454)
I want this version to be unhackable only I can't find any tutorials D: help?:scared:

PHP Code:

---

function rightClick():Void {
    //do whatever
}
var cm:ContextMenu = new ContextMenu();
cm.hideBuiltInItems();
cm.onSelect = rightClick;
menu = cm; 


---

that makes it so when the player right clicks //do whatever will trigger, just make it so it shows a loosing screen or links to the menu screen or something

Ohmygawd! Works like a dream~
