Harmn Sustain

Harmn Sustain is a vertical ball-bouncing cup-catching casual mobile game. Players pull back to charge and shoot the ball into the field; while the ball is flying, they drag a glowing cup to catch it and score. Tap empty areas to place bounce pads and change the trajectory; each caught ball earns one point, and when the ball lands and stops, the round ends. As the score increases, obstacles and moving bonus cups multiply, and states such as combos, magnetism, and adhesion alter the ball's path. Players need to coordinate flexibly among shot power, cup positioning, and pad placement, pursuing the satisfying thrill of continuous catches.
