first, press the green flag. next, press a difficulty. the text that appears in the middle of the screen while hovering over a difficulty tells what is special about it. you should see a black orb and a visible list. the black orb tells you stuff like the current components of the word found so far. the list is the letters you already used. don't worry, i made a safeguard so that you'll be safe from accidentally inputting a letter you did before and getting marked wrong for it.
