PeakPulseTap is a pure timing challenge around a breathing circle. The target expands and shrinks in a repeating cycle, and you score only if you tap at the maximum outline instant. Tap too early or too late and you earn a mistake. Three mistakes end the game. As your score rises, the pulse cycle accelerates, shrinking the safe window at peak size. Watch the outline grow, wait for the largest moment, then strike once with confidence. Restraint beats spam tapping. Feel the rhythm, trust the peak, and keep your hit timing clean as the pulse gets faster and less forgiving.
