/*
 * This is a word guessing game inspired by the New York Times' web game, Wordle. 
 * The player has six tries to correctly guess a word based on letter position feedback. 
 * The game is designed to test the player's vocabulary and deduction skills.
 * The game ends when the player either correctly guesses the word or runs out of guesses.
