Koibito No Nazo | Lover's Enigma (Prologue) Velocity, last 14 days: falling across 14 days, 0.01 to -0.00 (low -0.01, high 0.01).

Confidence 20%

Confidence is the share of Velocity’s four components that could be measured for this game, scaled down again when there is less than a fortnight to measure over. Here, ratings had a measurable acceleration on 2026-10-10. Topic views and comments did not. We also have itch.io chart positions for it, which is the fourth component. It was observed on 14 of the last 14 days. How this is computed.

Each line is scaled to its own change across these 30 days, so counters that differ by orders of magnitude can be compared by shape. The vertical gap is what matters: a line higher on the left took its change earlier. The real counts are in the legend, and the day-by-day numbers are below.

A blank change is not a zero: the scoring pass refuses a window whose nearest observation is too stale to compare, rather than differencing two points that are not seven days apart.

No devlog has been posted since we started watching on 2026-08-20. itch.io publishes only the most recent devlog date, so anything posted before then leaves no trace here.

We hold counters and metadata only. Nothing on the game’s own page — its description, its screenshots, its build — is republished here, and everything worth reading about it is behind those links.
