DELTARUNE · June 2026 to September 2026
Every hourly sample, 719 of them, with the daily peak drawn over the top. The saw-tooth is one day: a peak in the evening, a trough before dawn. 1 sample(s) came back as zero between two live hours and were dropped, so the faint line is broken where they were.
The highest number of people in the game at once, each month. Four, because four is as far back as the source keeps anything finer than one figure a month.
18 days, each one the highest figure that day. The source keeps no hourly detail this far back.
31 days, each one the highest figure that day. The source keeps no hourly detail this far back.
31 days as the curve, each the highest figure that day. Behind it, 473 hourly samples from 12 Aug, which is as far back as the source keeps every hour. 1 zero sample(s) dropped.
11 days as the curve, each the highest figure that day. Behind it, 246 hourly samples. Each dip is a night.
