/**** 
* GAME DESCRIPTION:
* Game Principle:
	* NAME: QUIZ COOL by Dalhem 2024
	* -There is a board filled with letters, where the player selects letters from a partially filled grid.
	* -With these letters, the player forms a word that appears below the grid, then validates their word.
	* -If the word is among the main list, it is valid, and the player earns points.
	* -The score obtained is proportional to the length of the word.
	* -These letters move randomly within the grid to empty spaces.
	* -If the word is not valid, the letters forming the word are returned to their original position in the grid.
	* -A new word is selected from the main list, shuffled and randomly dispatched in the empty cells.
	* -If there is no more space in the grid, the game is over.
* Game Areas:
	* The screen is divided into 5 main zones in the following descending order:
		1. Score area: displays the player's score.
		2. The grid: the letter grid (main grid).
		3. Word area: displays the word formed by the player (word grid).
		4. Validation area: button to validate the word or erase letters.
		5. Options area (or advertisement).
* Game Progression:
	* At the beginning of the game, the player choose a thema
	* Once the thema selected, the grid is almost empty, containing one  shuffled word.
	* The player can choose a letter in the grid by clicking on it.
	* The chosen letter is added to the word area.
	* The player can validate the word or erase a letter by clicking on the letter in the word, which then returns to its place in the grid.
	* When the player thinks he has formed a word, he can validate it with the validate button located below the word area.
	* If the word is valid, the player earns points, and the score is updated.
	* If the word is not valid, the letters forming the word are returned to their original position in the grid.
	* A new word appears randomly within the grid to empty spaces.
	* If there is no more space in the grid, the game is over.
