What it is

You step out at 400 metres. Below you are three places to land, worth 100, 250 and 600 — and the far one is deliberately further than you can reach in still air.

So the question is never where you want to go. It's whether you can still afford to get there.

Turning costs distance

Hands up, you glide almost three metres forward for every one you drop. Pull both toggles and you slow down — but you fall closer to one-and-a-half to one, so braking buys you time and takes away range. Turn hard and your sink rate climbs by half again.

Every input is a withdrawal. The good line isn't the one that points at the target, it's the one that arrives with something left over.

You can't plan the middle

The wind comes in three layers. Up high you're already in it, so you can read it off your own drift. Down low you can see it before you arrive, because there's a windsock at every zone.

The middle layer you cannot see at all. You find out what it's doing by flying into it, usually with about half your altitude already spent. That's the moment the run is actually decided — not at the door.

Two inputs, no menus. Touch is the real thing; mouse and keyboard both work as fallbacks on desktop.

What isn't settled yet

The descent works and the middle layer does its job. What's unproven is whether one run makes you want another — there's no career, no unlocks and nothing carried between jumps, so the reason to go again has to be the jump itself.
