Reading the room: level telemetry

Death maps

Opt-in telemetry plots every failed attempt as a point on the chamber map. A healthy chamber looks like a scatter — players dying everywhere as they explore. A sick chamber shows a dot-cluster: one spot eating everyone, which means the game is lying about what matters.

Twelve months of data produced a pattern the desk hadn't expected: players die most at decision points, not execution points. The hard part of a Rebound chamber is reading it, not threading it.

Three biomes that moved

Frost Hollow's glare: death clusters at invisible crystal spikes led to a lighting pass — deaths dropped 40% without touching difficulty. Ember Canyon's camera: a fixed angle hid a pendulum; the camera got smarter. Neon Reach's tutorial: players didn't understand polarity gates, so the game now teaches them in a safer room first.

Heatmaps don't tell you a chamber is bad. They tell you where the chamber is lying.

What we actually collect

Telemetry is opt-in, anonymous and gameplay-only: positions, attempts, deaths. No accounts, no device fingerprints, no names. The Privacy Policy documents the full schema in plain language.

The Masterclass has a full module on reading telemetry like a designer — the same dashboards the team uses.
