A one-thumb arcade game with a sharp core loop

Emberkeep — a one-thumb arcade game with a razor-sharp core loop. You are a warden of light orbiting a dying ember in the void: tap anywhere to instantly reverse your orbit direction and steer your light-arc into incoming crystal shards to shatter them before they crack the core. Build combo multipliers, catch golden shards, and trigger a Resonance power-up that widens your guard. A deterministic attract demo plays itself UI-free until your first tap.
