For grown-ups: The game starts with just 6 letters (s, a, t, p, i, n — the standard phonics starting set) and quietly adds more as your child clears rounds, remembering which letters they find tricky. Vowels are printed in red, like in phonics classrooms. "Listen" mode hides the letter so your child must recognize it from its name alone; "Sounds" mode asks by letter sound — real phonics practice. Between miles there are bonus rounds: spelling real words, or fixing a word with its missing vowel. Confetti Bombs are earned by doing well and knock the whole horde back, but never answer the question. Zombies gain ground on a steady clock and only correct answers push them back — wrong answers cost the streak, never the gap. Nobody gets hurt: zombies take a cartoon tumble and turn into flowers.
