Wordle is a word game that was created and developed by Welsh software engineer
Josh Wardle. In the original version of Wordle, players have six attempts to guess
a five-letter word, with feedback given for each guess in the form of coloured
tiles indicating when letters match or occupy the correct position.

In Animal Wordle, players have six attempts to guess a four-letter animal, with
feedback given for each guess indicating when letters match or occupy the correct
position. If the character is in the correct position, it is indicated with a hash
(#). If a character is correct, but in the wrong position, it is indicated with a
hyphen (-). If a character is incorrect, it is represented with a full stop (.).

Feedback will indicate:
- Correct letter and position: #
- Correct letter but wrong position: -
- Incorrect letter: .
