The game where you use strategy and anticipation to rid the air of smog. Predict where the particulate matter will cluster and use your Clean Air Bubbles to vaporize them. Be cautious of where you place your Clean Air Bubbles as they will divert the particulate matter.
Removing fine particles will increase your Percentage Cleared meter. Beat the level by having the meter reach the red line before you run out of Clear Air Bubbles.
