How to play

Read the incoming pressure. Choose one response. The effect lands first; the next pressure arrives after. A gauge at zero ends the run. Score rewards protecting the weakest gauge, not memorising one answer.

Why this is a game

It turns real systems tradeoffs into an authored, replayable decision loop. The same daily incident gives everyone a shared question; your decisions produce a different postmortem.
