Your light

The ring in the top-right corner is your light. Full to empty takes 10 seconds.

Inside your glow you see everything: fans, webs, bats.
Outside it the world falls to black. Only things that shine remain: gold stars, lanterns, crystals, the eyes of bats.
Below roughly 60% the moonlight is gone too. Below 25% your heartbeat kicks in, and the ring flashes red.
At 0% you fly blind. Running out of light does not end the run, but you will not see what hits you.

Pick-ups

Gold star +5

Refills your light completely. There is always one within reach of your current light, and they sit safely between hazards. Gold, steady, glowing.

Sparks +1

Tiny fireflies waiting in groups of three. Each one orbits you, adds a little light, and absorbs one hit instead of you. Up to three at a time; a fourth is worth +3.

Crystals Cave

Not a pick-up, but a refuge: while you fly beside a crystal cluster your light stops draining. Use them to catch your breath in the dark.

Hazards

Most hazards knock you toward the ground; only the ground and the spiked ceiling end the run.

Fan Forest · Storm

Spinning blades. A hit slams you downward hard, so flap at once. Faster in the storm.

Thorn vine Forest

Hangs from the ceiling at different lengths. Fly under it, or dash.

Swinging lantern Marsh · Storm

A lantern on a rope, swinging like a pendulum. Time your pass for the far end of the swing.

False star Marsh

Violet, jittery, and it drifts toward you. Touching one drains 30% of your light. Pass it untouched for +2.

Stalactite Cave

Cracks and trembles as you approach, then falls. When you hear the crack, go low.

Bat Cave

Roosts in dark pockets, red eyes glinting. If your light reaches it, it flees. If you arrive in the dark, it dives.

Stone gate Ruins

Two pillars with one gap, high or low. Line up early; the gap narrows on later laps.

Spider web Ruins

Sticks you for a second while your light drains 2.5× faster. A light-dash tears straight through.

Lightning & wind Storm

Lightning lights the whole peak for a moment, a free look at what is coming. The wind shoves you up and down; keep correcting.

The five zones

The run cycles through them and gets 5% faster each zone, up to +40%.

1
Whispering Forest
Fans spin in the dark. Thorns hang low.
2
Glow Marsh
Swinging lanterns and false stars over still water.
3
Crystal Cave
Falling stalactites, bats in the dark, crystals that hold your light.
4
Forgotten Ruins
Stone gates and the webs that span them.
5
Storm Peak
Lightning, wind and the fastest fans. Then it starts again.

Top 10

Every visitor gets a random firefly name, like Flying as Misty Moth 42 ✎. Tap the chip on the menu to choose your own; names are unique. Your best score is kept, and the Top 10 shows where you stand, even outside the ten.

Tips from the forest

Stay mid-height. The ground and the spikes are the only things that kill; a fan hit near the ground is what usually ends a run.
Spend light to save light. A dash through a web costs 14%; being stuck in one costs more.
Gold and still means safe. If a "star" wobbles and comes to you, it is a false one.
Keep bats in the light. Reach a roost with a bright glow and they leave. Arrive dark and they come for you.
Sparks first, then risks. With three sparks orbiting you can afford a blind pass or two for the bonus.
