A ghost game in a dark room. Shine a light to find dust ghosts and vacuum them up before your hearts run out.
Move the mouse or drag across the screen to shine your light around the dark room. Ghosts only show clearly inside the light. Tap a ghost to vacuum it up. Red and blue ghosts cost you a heart if they reach you, and you start with three. When the Shockwave button is charged, tap it or press the space bar to clear everything nearby. Grab power-ups, beat the Dust Lord boss and aim for a high score.
