Higher settings march the column along faster, send more ants per wave, add a color to juggle, give the burrow less room before it gives out, and put more ants in reach at once — eight at Beginner, twelve at Master, which is more to read but far more room to find a cascade in.

Ants in reach wear a single letter, each one different so a keypress is never ambiguous; press it and that ant spells out its word. The rest show only their color, which is what you plan cascades on.

Fades a keyboard across the play field and lights up the next key, color-coded by the finger that should press it. When stuck keeps it hidden until you miss three keys in a row, then shows it until you get one right.
