Nova rides a hand-drawn cyan line through a starry sky beneath the words “Draw lines. Fly forever.”

About

Nova never stops moving, and gravity never stops pulling. Draw glowing lines to catch her, carry her, and launch her across the sky. Bank off floating islands, ride geyser updrafts, thread jet streams, and escape gravity wells.

How far can you fly?

Nova flies through the green Emerald Drift world beneath the words “Ten worlds. One line.”

Nova crosses Aurora Reach beneath flowing jet streams and the words “Ride the jet streams.”

Ten worlds. One unbroken flight.

Fair play

No ads. No energy timers. No worlds or modes behind a paywall. The full ten-world flight is free. The optional one-time Supernova Edition adds the Supernova comet, Radiant Wake for every comet, and 2× photons from flight pickups, rings, and near misses. It does not add another revive.

The current localized price appears in the App Store. There are no consumable photon packs.

Glowline’s home screen appears beneath the words “No ads. Ever.”

Privacy and platform trust
