Keeping the environment clean is important, but it can get expensive INSTRUCTIONS: Your goal in this game is to earn one million dollars without polluting the environment too badly, press the 'control' button on the screen (not on your keyboard) to set fuel, filter or upgrade your factory. The bigger your factory are, the less pollution it causes for the same value of products, however, it causes more pollution because it is producing more products. Good fuel and filter pollute the environment less but they also makes you earn less money (and they even make you lose money in some cases). the sky and water will change colour if they are too badly polluted. The environment will get better over time if you use best fuel and filter (because they don't cause any pollution) Please note: This game is meant to be realistic and challenging, so please don't just use the best fuel and filter at the beginning of the game and waste all your money.
