A one-thumb arcade game with a sharp core loop

Orrery is a one-thumb arcade defense: a single tap swings a brass arm one quarter-turn clockwise to catch falling star-motes before they strike the Sun. The hook that sharpens the loop — the dial only turns forward, so every tap is a commitment you must plan and never overshoot. Chain deflects for combo, charge the Solar Ring, and survive the accelerating starfall.
