Flick balls, feel them collide, and watch them bounce off the walls with a tap of haptic feedback. No score. No goal. Just a toy. Flick the balls on screen and watch them scatter—bouncing off each other and the walls. Every collision sends a small haptic tap back to your fingertip. No score. No objective. Just a toy you touch because it feels good. ■ What you can do • Grab and flick balls with your finger • Balls collide and chain-react with physics • Haptic feedback on every wall and ball hit • Subtle sound and visual ripples on impact • Reset to start fresh ■ Mellow Pro (One-Time Purchase) • Switch between glass, rubber, and metal materials • Load scene presets that coordinate color, material, feel, and motion • Long-press empty space to attract or repel nearby balls • Change color presets • Adjust collision sound volume • Adjust haptic feel and intensity • Tune ball slipperiness • Tap empty space to add more balls • Tilt mode—gravity follows your phone • Adjust tilt gravity strength Pay once and keep Mellow Pro with no recurring charge.
