Direct answers
Mission briefing
What kind of game is Borrowed Gravity?
A single-player tactical orbital puzzle game that combines trajectory planning, strategy, and approachable spaceflight physics.
Do I need to calculate the physics?
No. The trajectory preview shows what your current burn will do. The challenge is choosing a satisfying route, not solving equations or matching microscopic inputs.
Can I play offline?
Yes. The campaign is fully playable offline and needs no account. Sign-in and cloud synchronization need a connection only when you choose to use them.
What data leaves my device?
Cloud progress is sent only after optional sign-in. Anonymous compact gameplay and product events are sent by default unless you turn analytics off in Settings → Privacy. Raw flight trajectories, route drawings, and session replays are not uploaded. See the privacy policy for details.
Can the campaign grow?
Yes. New handcrafted contracts can be added over time without changing how your existing progress is identified or saved.
Where can I report a difficult route or bug?
The support page includes troubleshooting and a direct email contact for gameplay, accessibility, battery, sync, and mission feedback.
A little thrust. A long way home.
Draw a burn, let gravity bend your route, and bring your ship home. Dock, replay the flight, and find a cleaner line.
The opening route of every sector is free to play. One permanent in-app purchase unlocks the remaining campaign routes. No ads or subscriptions.
