Zephyr Bolt

The sky-ports have drifted apart. The only road left between them is brass. You are the last clockwork courier on the Zephyr line — a wind-up runner with a satchel of post and a propeller bolted to your back. The catwalks scroll faster the deeper you go. Tap to vault the gaps. Hold to pop the propeller and glide over whatever is hissing below. Bank every cog you can reach along the way. TWO INPUTS, A LOT OF ROAD Tap vaults. Hold glides. That is the whole control scheme, and it stays readable at full speed. The difficulty comes from what the Works bolts onto the gantries, not from fighting the buttons. FOUR THINGS TRYING TO STOP YOU • Steam vents scald at deck level — a short hop clears them • Piston heads stand tall on the plating — those need a full vault • Crane arms swing overhead — stay on the deck and let them pass • Low girders hang across the walkway — do not leave the plating at all Read them wrong and the run ends. The Line Codex keeps the whole roster, with the right reaction for each. TWENTY LEGS AND A RUN WITH NO END Four worlds — the Low Gantries, Vent Row, the Crane Yard, and the climb to the Zephyr Spire. Each leg has a distance target and three stars: one for arriving, one for a real score, and one for arriving untouched. Clear three legs and the Perpetual Run opens: no finish line, no targets, just how far you can get before the line beats you. SPEND YOUR COGS TWO WAYS Mid-run, the bar under the track sells what you need right now — Brass Bulwark soaks one impact, Governor Spring drops the conveyor to 65%, Steam Surge ploughs through everything for four seconds, and Rewind Spool winds a crash back two and a half seconds. Back at the Workshop, cogs buy permanent fittings instead: longer propeller glide, a lodestone that pulls loose cogs in as you pass, gearing that counts your run for more, and extra hull plating between you and the vents. Every fitting is on the courier from your very next run. A CRATE A DAY One supply crate per calendar day, with a live countdown to the next. Fourteen commendations track the long haul — first delivery, fifty clean vaults without touching the propeller, a leg finished without a scratch, a deep run past 1,200 metres. COMPLETELY OFFLINE No account. No sign-in. No network. No ads, no purchases, no interruptions. Zephyr Bolt works in airplane mode on the first launch and every launch after it, and everything you earn stays on your device. BUILT TO BE READABLE Four assists on the Controls screen: shape tags over every hazard, brighter deck edges, damped flashes, and an ambient-motion switch. Turn on what helps and leave the rest. Run the line. Keep the post moving.
