In a good sequence, you map every step like a choreography, then inject a single variable that breaks the rhythm—an unexpected sensor glitch, a new guard's shift, a wind that alters a light. Keep the core beats tight, but let that variable force the player to adapt, to feel the tension you’ve set up. The trick is to make the rhythm feel inevitable, yet leave a single twist that can shift the whole dance. That’s how you marry precision with suspense.
