Rotor Pulsy

Deep in an abstract core of lava cracks and dark stone, a dual-ring rotor waits for timed energy. Bright windows open on a cycle. Short-tap the rotor or the bottom ring while a window is lit to feed spin. Presses outside the window raise drag and drain power faster. Holdouts that empty the energy bar stop the rotor and end the run. Score grows with seconds survived, and clean window chains raise a multiplier. Later windows shrink, and reverse-torque pulses ask you to delay the tap on purpose. There is no audio pack by default; the loop is visual and tactile. English UI only, portrait, start from a lobby with the rotor centered and a start control on the left. In play you watch duration on top and an energy column on the right. Come back when you want a calm, pulse-driven endless session that rewards patience over frantic tapping.
