Concurrent players on Steam, one reading a day at about 15:00 UTC since Sep 29, 2026. Before then readings were taken at different times of day, spanning 0 hours, and Steam concurrency runs about 1.8x higher at its daily high than at its low — so some of the movement across that stretch is the clock, not the game.
Shaded: Steam sales and festivals this game was in (the Events tab has each one).
