Press anywhere on the screen, drag backwards, and let go. The further back you drag, the harder the throw, and the angle of the drag is the angle of the launch. A very short drag, or one that points forwards, is read as a mis-touch and does not throw — so you can rest a thumb on the screen without losing a plane.

That is the skim. Fly within about four metres of the ground or a rooftop, fast, and it starts counting up — every coin you take while it is running is worth that many times its face value, to a maximum of five. Climb above roughly nine metres and it resets to nothing. Flying low is the whole economy of the game.

No. There is no failure state in Paper Skyline and nothing is ever wasted. Throw again: the plane keeps the upgrades you have already folded in, and every flight earns more. A city takes as many throws as it takes.

That is the design, not a bug. Every city hands you a blank sheet — coins go back to zero and the upgrades come back out. What you keep is the distance you have already flown, the cities you have charted, and the artifacts you have found. A city is a build you commit to, which only works if you have to make the choice again.

Each city hides its own: one high enough that you need altitude to reach it, one at middling height, and one that only a rooftop skim will take you past. They do not move, and they do not come back once found — they stay with you through every reset and fill in your atlas.

Yes, always. Paper Skyline makes no network requests at all. It plays exactly the same in aeroplane mode, which is a reasonable place to play a game about paper aeroplanes.

Not today. There is no account and no cloud save, so each device keeps its own progress. That is the same decision that means the game asks nothing of you and stores nothing about you — see the privacy policy.

Delete the app. Everything the game has ever written lives in that app's own storage on your device, so removing it removes all of it. There is no copy on a server to ask us about.

The game sends no crash reports, so we will not know unless you tell us. Write to support@paperskyline.org with your device, your OS version, and what you were doing at the time — which city, and whether the plane was in the air.
