+* GAME DESCRIPTION:
+* Game Principle:
+	* -There is a board filled with words, 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 words on the board, it is valid, and the player earns points.
+	* -The score obtained is proportional to the length of the word.
+	* -Above the grid, there are letters randomly taken from the word board.
+	* -These letters move randomly within the grid to empty spaces.
+	* -New letters are placed above the grid.
+	* -If the word is not valid, the letters forming the word are returned to their original position in the grid.
+	* -The letters above the grid move randomly within the grid to empty spaces.
+	* -If there is no more space in the grid, the game is over.
+* Game Areas:
+	* The screen is divided into 6 main zones in the following descending order:
+		1. Score area: displays the player's score.
+		2. Next letters area: displays the letters that will fall into the grid.
+		3. The grid: the letter grid.
+		4. Word area: displays the word formed by the player.
+		5. Validation area: button to validate the word or erase letters.
+		6. Options area (or advertisement).
+* Game Progression:
+	* At the start of the game, the grid is almost full, containing 5 letters.
+	* Above the grid, there are 4 letters randomly taken from the word board.
+	* 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 they have formed a word, they 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.
+	* The letters located above the grid move randomly within the grid to empty spaces.
+	* New letters are added above the grid.
+	* If the word is not valid, the letters forming the word are returned to their original position in the grid.
+	* The letters located above the grid move randomly within the grid to empty spaces.
+	* If there is no more space in the grid, the game is over.
