We had a question: when is a puzzle game too hard? The usual answer — “when players drop off” — is too slow and too lossy. People rage-quit quietly. They don’t fill out forms.

So we built a little tool. It sits on the test build’s telemetry pipeline and watches for a single signal: keypress frequency on the delete key within 500ms of a failed signal sync. That’s it. That’s the whole thing.
