Orrery

A solar system turns below you, drawn in pure white vector light. In your hand: a comet.

Throw it, and the star pulls it in. Every planet tugs at it as it passes. Swing past a world and slingshot onward; thread a line through three beacons with a single throw. Each of Orrery's 99 levels is a small puzzle of real gravity, and every one is proven solvable in par.

• 99 levels in nine chapters, each bringing a new idea: aligned beacons, swaying beacons, crowded moons, linked pairs, golden beacons that only count after a chain, numbered sequences and more.
• Real orbital physics: the star and every planet and moon pull on every comet, and planets move at their true orbital speeds.
• Combos on the Fibonacci sequence. Chain slingshots and strikes in one flight and keep a streak going across throws to multiply your score and earn comets back.
• Rate yourself against par on every level, and chase three golden spirals on all 99.
• Every size and distance in the game is built on the golden ratio, from the spacing of the orbits to the letters on the screen.
• A sparse twelve-tone heartbeat score that quickens the longer you think.

You stand still and the system stays where it is, so it's comfortable to play seated or standing.
