Stellar Ascent is a pixel-art game for iPhone. Your ship climbs from Earth’s sky toward the outer planets on its own. You steer it, keep the fuel tank from running dry and dodge whatever crosses your path.

Common questions
How do I play?
The ship climbs by itself. Drag your finger left or right anywhere on the screen to steer, grab fuel to refill the tank and avoid every obstacle: one hit ends the run. To see the tutorial again, tap Help on the main menu.
What do the power-ups do?
The shield protects your ship from collisions, the magnet pulls coins and fuel toward you, and the laser blasts through obstacles. Only one power-up is active at a time.
How do I get new ships?
Spend the coins you collect in flight on new ships in the Hangar. Prize ships can’t be bought: you unlock them by reaching the altitude shown in the Hangar in a single run.
Where is my progress saved?
Only on your iPhone: your best altitude, coins, ships and settings. There are no accounts or cloud sync, so deleting the game erases your progress. Restoring your iPhone from a backup, or setting up a new iPhone from one, usually brings it back.
How do I turn off sound or vibration?
Pause during a flight and use the Sound & Music and Vibration switches.
Do I need an internet connection?
No. The game works completely offline.
Does the game collect my data?
No. There are no accounts, ads, analytics or tracking. The privacy policy has the details.
