A field on a January morning, twenty to ten. It started snowing at about one and it hasn't quite stopped. Everything that crossed the field in the night is still written on it. Snow keeps falling into every print, so the older a track is, the softer and shallower it looks: the fox's line from before six is a row of soft dimples, the hare's bounds from an hour ago are still sharp. Where two tracks cross, the one on top came later. Between them you can work out the order of the night. A fox, two roe deer that stopped under the oak and scraped for acorns, someone from the cottage who walked out to the middle of the field and lay down, a hare, a crow, small birds under the holly. And by the top hedge, something from before any of them. The person from Gate Cottage has left a note on the gate. Your own prints are the newest in the field. They fill in too, at the same real rate as everything else, so you won't see it happen. There is no clock and nothing to finish. The field, cottage and animals are invented; the tracks follow how these animals really move. Controls: WASD or arrow keys to walk (Shift to walk faster), mouse to look (click once to capture it). C crouches so you can look closely at the prints. X lies you down on your back in the snow; while lying, A or D sweeps your arms and legs, and X gets you up again (the shape stays). Hold Z to look closer. E reads the note when you're beside the gate. Esc leaves. The sound (wind, your feet, a crow) is quiet and synthesised, made by an AI that can't hear it. No outside assets.
