Gravity Duel vs Gravity Courier

Gravity Duel is a compact arcade space battle built around motion, timing, and orbital shots. Fly around a central gravity well, rotate your ship, thrust into position, and fire at the right moment. Projectiles curve through the arena, so every shot is part aim and part prediction. Features: - Gravity-influenced projectile paths - Simple touch controls - Quick matches against an AI rival - First-to-five scoring - iPhone and iPad support - No accounts, ads, tracking, or network required It is an original modern arcade duel inspired by the feel of classic space combat, with clean visuals and fast restartable rounds.

You are a space delivery controller. Your only job: choose when, which way, and how hard to launch — then let gravity do the rest. Gravity Courier is a minimalist orbital puzzle built on real physics. The Sun, planets, and moons are genuinely orbiting in real time. There is no joystick, no thrust-and-steer. You read the dance of the planets, pull back a slingshot to aim, pick the launch moment, and fire. From there, gravity alone bends your probe's path — so a straight shot will never work. Predict the curve, use a planet's pull, and arrive exactly on target. WHY IT FEELS DIFFERENT • Real orbital mechanics — Keplerian planet motion + true n-body gravity on your probe. Deterministic, fair, and endlessly satisfying to "solve." • One decision, infinite depth — only date, direction, and thrust. Easy to grasp, hard to master. • A living solar system — Mercury to Neptune orbit at their own speeds. Change the launch date and the whole board lines up differently. MISSIONS ACROSS THE SOLAR SYSTEM • Orbit — loop a planet or moon without escaping or crashing • Flyby & return — swing around the Moon's far side and let gravity sling you home • Landing — enter a gravity well and settle into a soft touchdown • Reach — time an interplanetary transfer to meet a moving planet where it will be • Gravity assist — skim a giant planet and steal a free push • Orbital cleanup — ram drifting space debris before it spreads FEATURES • 90+ handcrafted missions across the Sun, Moon, Venus, Mars, Jupiter, Saturn, and the outer planets • Predicted-path preview with a closest-approach marker — line up the gap and you'll hit • Reserve a mid-flight boost on your trajectory, or fire it by hand • Star ratings reward fuel economy and fast transfers — chase that 3-star run • Replay any flight and share it as a trajectory image card • Clean, quiet, starfield aesthetic with a calming soundtrack • 13 languages • Play offline • One-time "Remove Ads" available No timers pushing you. No pay-to-win. Just you, the planets, and one perfect launch. Read the orbits. Launch right. Safe orbits, courier.
