/*
 * Wordle Face
 * A port of NY Times' Wordle game (https://www.nytimes.com/games/wordle/index.html)
 * A random 5 letter word is chosen and you have WORDLE_MAX_ATTEMPTS attempts to guess it.
 * Each guess must be a valid 5-letter word found in _legal_words in the C file.
 * The only letters used are _valid_letters, also found in the C file.
 * After a guess, the letters in the correct spot will remain, 
 * and the letters found in the word, but in the incorrect spot will blink.
 * The screen after the title screen if a new game is started shows the streak of games won in a row.
 * 
 * If USE_DAILY_STREAK is set to True, then the game can only be played once per day,
 *                  and the streak resets to 0 if a day goes by without playing the game.
 * 
 * Controls:
 *    Light Press
 *        If Playing: Next letter
 *        Else: Next screen
 *    Light Hold
 *        If Playing: Previous letter
 *        Else: None
 *
 *    Alarm Press
 *        If Playing: Next position
 *        Else: Next screen
 *    Alarm Hold
 *        If Playing: Previous position
 *        Else: None
