TunnelDash

TunnelDash is an endless vertical tunnel run. Tap to switch your ball between upward and downward motion while red blocks scroll toward you and slide left and right inside the tunnel. Survive for one point each second. Touching any moving block ends the run immediately. As your score climbs, the tunnel narrows, blocks spawn denser, and their sideways speed rises. Time your switches early, stay off crowded heights, and avoid panic taps near walls. Smooth vertical control under rising sideways threats decides how far each endless tunnel dash can go.
