A scrollbar-only physics game. Tune the launch, shoot the marble, and try to make it orbit or hit the target ring.

Goal: hit the blue target ring OR keep the marble orbiting without collision/escape.

The trick: speed aimed directly inward usually crashes. Sideways velocity creates orbit. Too much speed escapes.

Visual scale is exaggerated. Real values are SI units. Central sphere is fixed for gameplay.
