// Cloned by Mathias Bazin on 13 Jun 2018 from World "Game of Crowns season 2 Third Person View" by Mathias Bazin 
// Please leave this clone trail here.
 


// Cloned by Mathias Bazin on 31 May 2018 from World "Game of Crowns" by Niamh Byrne 
// Please leave this clone trail here.
 

// =============================================================================================
//the idea:
//this game is based on the game of thrones world Winterfall-. snow,castle,queen,fireball
//The queen needs to collect all her crowns
//the queen needs to avoid being trapped by the fireball
//When the queen steps into the crown the crown disappears 
//there are 8 crowns to collect
//The user acts as the mind as they control the queen
// =============================================================================================


// =============================================================================================
//Aim:
//Collect all the crowns
//Dont get trapped into a corner by the fireball
//Collect crowns within 200 seconds
//
// =============================================================================================

//===================================================================
//Season 2 changes :
//Queen and crowns are bigger
//Queen turns to face the direction she is heading
//Changed some raw values into constants
//added some time to collect the crowns (it was hard !)
//===================================================================

// World must define these:
