Giltlock Minute is a three-floor tactical stealth game contained entirely in the Firefox popup. Each move, wait, switch, or thrown decoy advances the guards by one beat. Guards see along straight, unobstructed corridors: three tiles in light, one tile after the power is cut. Dark shadow tiles conceal the player beyond a guard's adjacent tile. Later floors introduce a key-operated gate and a second patrol. A decoy can be thrown onto a nearby floor tile to draw guards away for two beats. Recover each floor's exhibit and return to its marked exit. Detection restarts only the current floor; there are no lives to lose. A clean extraction report records beats, detections, and decoy use. Progress is saved locally after each completed turn.
