Each shift gives you a dedicated reading window before you decide when to begin. BUILD YOUR SCORE Tap early for reaction bonuses, maintain combos for larger multipliers, and survive rule shifts for bonus points. Earn Bronze, Silver, and Gold medals by balancing accuracy with speed. UNLOCK POWER-UPS Complete levels, earn medals, build combos, and reach new milestones to unlock helpful abilities.
