Reactor manual

Fire three prime lasers whose energy adds up to the core target. Repetition is allowed, and 2 counts as a prime.

• · Too much energy triggers an overcharge — vent a beam fast.
• · Too little energy burns an energy cell.
• · Later sectors add timers, rotating emitters, locked primes and bosses.
• · Speed, flawless runs, triple primes and rare combos boost your score.
