Steam Engine Governor
A mobile physics puzzle where two brass sliders (governor ball mass and linkage gain) drive a real second-order feedback loop controlling a steam engine's speed. Load events disturb the engine; the player tunes the governor so a live speed trace recovers instead of hunting into oscillation, across 12 scenarios from a steady mill to a sawmill with sudden bites. Ends with a shareable result card of the final trace.
