You play as a space janitor who flies through orbital debris on a jet powered broom to keep the sky tidy. Move the character with the mouse, a finger on touch screens, or the arrow and WASD keys to reach nearby debris and sweep it away. Every piece collected adds to your score and a streak of clean catches raises your multiplier. Spiky hazardous wreckage also drifts through the field and colliding with it costs a life so it is safer to steer around. Grab the floating bonuses along the way, a shield blocks one hit, a magnet pulls nearby debris toward you, and a clock slows everything down for a few seconds. Debris grows faster and more frequent as time passes so staying focused really matters. The run ends once all lives are lost and your final score is compared against your best result.
