Deep in a glow cavern, crystals slide a zigzag belt that reverses direction on each shelf. Tap bright phosphorus gems and skip dull waste rock while a timer presses your quota. Speed pulses surge without warning and force quicker reactions under pressure. Wrong taps or a finished clock ends the run at once. Harder caves shorten time and spike more often. Grab enough crystals before the lights fade and push deeper into the cavern for brighter, faster belts and tighter clocks. Watch for speed pulses, skip waste rock, and finish the crystal quota before the cavern timer runs dry.
Tap glowing crystals on the zigzag cave belt before the timer ends.
