Gravity Field is a thousand small points of light, and your finger is the force they answer to. Drag, and the whole field bends toward you like iron filings finding a magnet. Tap, and it bursts apart and settles again. There is nothing to score and nothing to read. It is just a field of matter that responds to you, instantly, however you push it.
Why it exists
Some toys are for winning and some are just for the feeling of your own hand changing something. Gravity Field is the second kind. It is the quiet pleasure of stirring a crowd of particles and watching them swirl, gather and fly, the same reason it is hard to stop dragging your fingers through sand or water. Real forces are doing the work underneath, so it never quite moves the way you expect, and that tiny surprise is what keeps you there.
How to play
Drag to pull the field toward your finger. Tap to burst it. Change the palette and the strength of the pull, and find the setting that is most satisfying to stir. There is no right way and no end, so stay as long as it is calming and leave when it stops being.
