A one-thumb arcade game with a sharp core loop

Ember Orbit is a one-thumb arcade game with a razor-sharp core loop: the world rotates, your spark holds at the bottom of two orbit rings, and a single tap shifts it between the inner and outer ring. Each ember-gate sweeps past with a hole at exactly one ring — be on that ring when it arrives, thread the gap, and grab glowing motes to build a score multiplier as the gates accelerate.
