Tap to jump once (or press Space / ↑). After that the ember bounces by itself every time it lands, and all you do is steer.
Press anywhere and drag left or right to steer: the further you drag, the harder it steers. On a computer, drag with the mouse, or hold ← / → (or A / D). You can steer the whole time you're in the air.
Speed makes height. The faster the ember is moving sideways when it lands, the higher and farther the next bounce. Steer the way you're moving to build speed, or against it to slow down and land short. Side walls bounce you back at the same speed.
Combos: a bounce that lands 2 or more new ledges above your best builds a combo. A shorter bounce ends it and scores (ledges in the combo)² × 5, so long combos are where the big points are.
The view starts rising 3 seconds after your first jump and gets faster every spire. Drop off the bottom and you lose a spark (you have 3). You reappear on a ledge with every point and metre kept, and start bouncing again after 2 seconds (tap to go sooner). Land on the beacon at the top to light it and move on.
There are 6 spires, each adding one thing: glass ledges that bounce you 25% higher, ash ledges that break after one bounce, rails that slide side to side, gust bands that push you sideways (shown by streaks), and finally all of them on narrow ledges.
Scoring: 10 per new ledge reached, combos as above, 50 per glowing ember mote, 500 × spire number for each beacon, and 1,000 per spark left when you light the last one.
P pauses, M mutes.
