The instructions are in the game. Click the green flag a bunch of times real fast. It's kind of glitchy. Have fun! P.S. If anyone can figure out how I can recognize if there are doubles in the code and therefore only award a single correct color in the correct position a black peg and not also a white peg, do tell in the comments section. Right now I have it so that there can't be any doubles in the code, but that's not actually correct.
Thanks to Johann Sebastian Bach for the music, Minuet in G Major, played by me. Thanks also to Mordecai Meirowitz, the mastermind behind MASTERMIND.
