About

Starship Rescue

Read full description

Drag to aim. Let go. Gravity does the rest. There is no thrust and no steering. You get one decision — which way to fire and how hard — and then you watch the physics answer it. Your ship curves around planets, threads past orbiting moons, and either finds the wormhole or doesn't. Five stranded crew sit along the route. Reaching the wormhole clears the sector, but three of the five have to come with you before the next one opens. Collecting all five is the real problem. EVERY SECTOR IS SOLVED BEFORE YOU SEE IT Levels here aren't hand-placed and hoped over. Each is built from planets alone, and then a solver brute-forces nearly two thousand launches through the same physics that flies your ship. It keeps only the routes that reach the wormhole with real clearance and a flight you can actually watch, and lays the crew along one that works. Where moons are involved it goes further, tuning their orbits until there is a window wide enough for a human to aim in — because a level you can only pass in a tenth of a second is a lottery, not a puzzle. If a sector can't be proven beatable, it doesn't ship. TIMING, NOT TWITCH From sector nine, moons orbit the planets. They block your path but never pull on it, and they keep moving while you line up the shot. So when you release matters as much as where you point. Watch the rhythm. Wait for the gap. AN HONEST AIM LINE The preview arc is a real trajectory from the same integrator that flies the ship — not an approximation that quietly drifts near a planet. It stops short of the answer, but as far as it goes, it tells you the truth. A VECTOR DISPLAY Wireframe rock, phosphor bloom, and a grid that bends under gravity. Every mark on screen is line work; there isn't a texture in the game. BUILT TO BE PLAYED WITH ONE THUMB No account. No network. Plays offline, in portrait, one-handed. FREE TO START The first fifteen sectors are free, all the way to the sector your guns arrive on. One purchase unlocks the other eighty-five. No ads, no subscriptions, no second helping — that purchase is the only thing this game ever sells. ACCESSIBILITY Reduced motion stops the grid warp and the spin. High contrast thickens the strokes and cuts the bloom. Line weight and glow are yours to set. Each way of losing sounds different, so an outcome is never carried by colour alone.

Verdict

The call

The clearest difference is ads: Starship Rescue at none against OCO's shown. Starship Rescue also leads on update cadence (every 4 days vs every 5 weeks). OCO's advantage is chart position (#184 vs unranked) and device support (3 vs 1). On price and in-app purchases there is nothing between them.
