One Breath City

Luma is a city that only exists in time while you are touching the screen.

Press and hold — people walk, trains run, lifts climb, the whole diorama comes to life. Lift your finger and everything freezes on the exact same instant: mid-step, mid-turn, mid-fall. You are not moving the pieces. You are editing the moment.

Every level is a small living machine. Read it, then give it the breaths it needs — start a chain of cranes and gates, stop a car just short of a train, ride a lift to a rooftop, send your own echo back in time to hold a door open. Some levels give you only a handful of breaths. Spend them well.

• 82 hand-built levels across 8 chapters, each introducing one idea: first breath, traffic, machines, heights, two districts at once, time zones, and memory
• A new Daily Breath puzzle every day — the same for everyone, generated on-device, playable offline
• Endless City — a run of fresh procedural puzzles that opens once the story is done
• Rated in breaths, not stars: ○ ○ ○ for a single perfect run
• Calm by design — no timers, no lives, restart in under a second, and a soundtrack that fades to silence whenever the city holds still
