Objective

Carry the post along a fleet of airships at dusk. Every deck sinks the moment you stand on it, so the only way on is forward.

Controls

Hold anywhere on the screen (Space, Enter or the mouse button on desktop) to charge the leap, and release to launch. The gold marker ahead of the courier shows exactly where it will land: the leap grows from 1.2 to 5.2 units at 2.6 units per second of hold. The deck you are standing on holds station while you charge; the one you are aiming at drifts, so lead it.

Scoring

+10 for a deck, +5 more for landing in the middle of it, +5 for a mail satchel caught in the arc. Clear a deck and land on the one beyond it and both count.

The squeeze

After two seconds the gaps stretch from 1.9 to 3.1 units, the decks narrow, they drift faster, and your own deck sinks quicker — 5.2 seconds of thinking time at the start, 2.2 at the end. Miss a deck, or ride yours down into the cloud, and the run is over.
