Gravity Wells
No walls, no fixed wells — the only gravity well is your own cursor. Move it around
to fling every ball's slingshot orbit wherever you want, each one trailing a rainbow
streak. Get pulled in too close and a ball bursts into voxels and reappears from the
edge.

How it works: the well tracks your mouse (or your finger on touch)
every frame and pulls on every ball with an inverse-square force toward its center,
same shape as real gravity — the closer a ball gets, the harder it's pulled, which is
what produces the slingshot: a ball swinging past the well gets whipped around and
flung out much faster than it arrived, then coasts (losing no energy, since there's
no friction) until it swings back through your reach again. The "AOE" slider sets how
far that pull actually reaches — outside the dashed ring a ball feels nothing at all,
inside it the usual inverse-square force applies, so a bigger AOE doesn't just look
bigger, it genuinely gives you a wider net to catch and redirect balls with. Balls
bounce softly off the canvas edges to stay on screen. Every frame's position is
recorded with a cycling hue, same rainbow-afterimage technique as Growing Trail Ball,
so each orbit leaves a fading colored streak behind it. Get pulled within the well's
small solid core and a ball is "captured" — it bursts into voxels and a fresh ball
reappears from a random edge with a new trajectory, so the scene never fully settles.
