This is pretty fun. Kinda wonder if it has to be so slow to update given that everything is local. Or does it have to do a round trip to the server on every click?<p>Bug report: this gives a yellow square for a letter that should be gray, when that letter occurs elsewhere in the word and the guess already has it in the right place. So e.g. if the word is ABCDE and you guess ABCDD it gives green for the first D and yellow for the second D (which should be gray).
