Add a visual indicator to Balloon Shoot when balloons are about to despawn

A common issue I have with Balloon Shoot is I’ll try to aim for the highest balloons and they’ll suddenly despawn since they reached their max height.

It’d be greatly helpful if there was a visual indicator when balloons are about to reach max height, like a forcefield at the max height that appears when they get close, so I can more easily focus on popping balloons that aren’t going to vanish within the next second.
