The palms never stop — keep the sand clear

Sets how fast the coconuts come and how much sand there is to fill — but the part you will feel is the crew: five crabs on Beginner down to three on Master. Fewer crabs is not just harder, it changes what you are deciding.

Fades a keyboard across the beach and lights up every letter currently in play, 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.
