HOW TO PLAY

Bring every system back online

Protect integrity

A wrong answer causes a fault and removes one integrity point.

Faults return

Missed challenges come back later. The system only goes online when every challenge is mastered.

Clean compile

Correct answers in a row build a streak and increase your score.

Run diagnostics

You have two hints per mission. Hints help you think without costing stars.

Keyboard: 1–4 chooses an answer, H runs a diagnostic, Enter continues after feedback.
