ProgressBarLock turns timing into a moving target challenge. A horizontal progress bar scrolls continuously, and a green zone marks the only safe area. Tap the screen when the moving marker enters that green zone to lock your score. Tap outside the zone and you make a mistake. Three mistakes end the run. As you progress, the green zone becomes narrower and the bar moves faster, leaving very little room for error. Success depends on watching the marker closely and tapping at the right moment, not too early and not too late. It feels simple at first, but higher levels demand real focus.
