About

Between Stars

Features
Read full description

Between Stars is a calm gravity puzzle in space. Guide a ship to the glowing blue goal using the pull of planets. Play all 7 levels in “Origins” free, with no ads. One optional purchase permanently unlocks the other 20 levels and every future paid level pack. Aim the ship, launch, and watch gravity bend the route. Every level has a one-burn solution: use one continuous thrust activation, then let gravity carry the ship to the destination without more thrust. Finding it is a challenge, not a requirement — you can use additional thrust whenever you need to correct your course. When you complete a level, you earn points called lumen. How many you earn depends only on your total thrust time: less thrust means more lumen. You can wait before launch without losing lumen. Letting gravity carry the ship doesn’t cost lumen either. Your highest-scoring flight on each level is automatically saved for replay. As you complete levels, these replays form a personal collection you can watch anytime and show to friends. Every successful flight is also saved in “Your paths.” Open it from a completed level to see all your successful routes together. The game includes 27 hand-tuned puzzles divided into three level packs. “Origins” centers on planets that pull the ship. “Deep Gravity” adds moving planets, pulsing gravity fields, and two-planet systems. “Aurora” introduces repulsors: fields that push the ship away instead of pulling it closer. There are no time limits, no lives, and no fuel limits. Retries are unlimited. Experiment at your own pace. Optional hints show a successful route only when you ask. • A calm ambient soundtrack for each pack • Play in English, French, German, Spanish, Italian, or Portuguese • No ads, accounts, tracking, or subscriptions
